If a signatureEncoding is specified, the signature is expected to be a string; otherwise signature is expected to be a Buffer , TypedArray , or DataView. The verify object can not be used again after verify. Multiple calls to verify. Because public keys can be derived from private keys, a private key may be passed instead of a public key.

Returns information about this certificate using the legacy certificate object encoding. Verifies that this certificate was signed by the given public key. Does not perform any other validation checks on the certificate. The default encoding to use for functions that can take either strings or buffers. Property for checking and controlling whether a FIPS compliant crypto provider is currently in use. This property is deprecated. Please use crypto.

The authTagLength option can now be used to produce shorter authentication tags in GCM mode and defaults to 16 bytes. Creates and returns a Cipher object that uses the given algorithm and password. In that case, the authTagLength option is required and specifies the length of the authentication tag in bytes, see CCM mode. In GCM mode, the authTagLength option is not required but can be used to set the length of the authentication tag that will be returned by getAuthTag and defaults to 16 bytes.

On recent OpenSSL releases, openssl list -cipher-algorithms openssl list-cipher-algorithms for older versions of OpenSSL will display the available cipher algorithms. The password is used to derive the cipher key and initialization vector IV. The implementation of crypto.

The lack of salt allows dictionary attacks as the same password always creates the same key. The low iteration count and non-cryptographically secure hash algorithm allow passwords to be tested very rapidly. Users should not use ciphers with counter mode e.

A warning is emitted when they are used in order to avoid the risk of IV reuse that causes vulnerabilities. The iv parameter may now be null for ciphers which do not need an initialization vector. Creates and returns a Cipher object, with the given algorithm , key and initialization vector iv.

The key is the raw key used by the algorithm and iv is an initialization vector. The key may optionally be a KeyObject of type secret. If the cipher does not need an initialization vector, iv may be null. When passing strings for key or iv , please consider caveats when using strings as inputs to cryptographic APIs.

Initialization vectors should be unpredictable and unique; ideally, they will be cryptographically random. They do not have to be secret: IVs are typically just added to ciphertext messages unencrypted. It may sound contradictory that something has to be unpredictable and unique, but does not have to be secret; remember that an attacker must not be able to predict ahead of time what a given IV will be. Creates and returns a Decipher object that uses the given algorithm and password key.

Creates and returns a Decipher object that uses the given algorithm , key and initialization vector iv. In GCM mode, the authTagLength option is not required but can be used to restrict accepted authentication tags to those with the specified length. Creates a DiffieHellman key exchange object using the supplied prime and an optional specific generator. The generator argument can be a number, string, or Buffer.

If generator is not specified, the value 2 is used. If primeEncoding is specified, prime is expected to be a string; otherwise a Buffer , TypedArray , or DataView is expected. If generatorEncoding is specified, generator is expected to be a string; otherwise a number, Buffer , TypedArray , or DataView is expected. Creates a DiffieHellman key exchange object and generates a prime of primeLength bits using an optional specific numeric generator.

An alias for crypto. Creates and returns a Hash object that can be used to generate hash digests using the given algorithm. Optional options argument controls stream behavior. The algorithm is dependent on the available algorithms supported by the version of OpenSSL on the platform. On recent releases of OpenSSL, openssl list -digest-algorithms openssl list-message-digest-algorithms for older versions of OpenSSL will display the available digest algorithms.

The key can also be an ArrayBuffer or CryptoKey. The encoding option was added. Creates and returns an Hmac object that uses the given algorithm and key. If it is a KeyObject , its type must be secret. The key can also be an ArrayBuffer. Creates and returns a new key object containing a private key. If the private key is encrypted, a passphrase must be specified. The length of the passphrase is limited to bytes.

The key argument can now be a KeyObject with type private. Creates and returns a new key object containing a public key. In that case, this function behaves as if crypto. The key can also be an ArrayBuffer or string. The encoding argument was added. Creates and returns a new key object containing a secret key for symmetric encryption or Hmac. Creates and returns a Sign object that uses the given algorithm.

Optional options argument controls the stream. Writable behavior. This will use the corresponding digest algorithm. Creates and returns a Verify object that uses the given algorithm. Computes the Diffie-Hellman secret based on a privateKey and a publicKey. Asynchronously generates a new random secret key of the given length. The type will determine which validations will be performed on the length. The generateKeyPair and generateKeyPairSync functions now produce key objects if no encoding was specified.

Generates a new asymmetric key pair of the given type. Otherwise, the respective part of the key is returned as a KeyObject. If this method is invoked as its util. When PEM encoding was selected, the respective key will be a string, otherwise it will be a buffer containing the data encoded as DER.

Synchronously generates a new random secret key of the given length. If options. The options. Both options. Some ciphers accept variable length keys and initialization vectors. By default, the crypto. To test if a given key length or iv length is acceptable for given cipher, use the keyLength and ivLength options.

If the given values are unacceptable, undefined will be returned. Creates a predefined DiffieHellmanGroup key exchange object. The returned object mimics the interface of objects created by crypto. The advantage of using this method is that the parties do not have to generate nor exchange a group modulus beforehand, saving both processor and communication time. The given ikm , salt and info are used with the digest to derive a key of keylen bytes.

The supplied callback function is called with two arguments: err and derivedKey. If an errors occurs while deriving the key, err will be set; otherwise err will be null. An error will be thrown if any of the input arguments specify invalid values or types. An error will be thrown if any of the input arguments specify invalid values or types, or if the derived key cannot be generated. The iterations parameter is now restricted to positive values.

Earlier releases treated other values as one. Calling this function without passing the digest parameter is deprecated now and will emit a warning. The default encoding for password if it is a string changed from binary to utf8. A selected HMAC digest algorithm specified by digest is applied to derive a key of the requested byte length keylen from the password , salt and iterations. If an error occurs while deriving the key, err will be set; otherwise err will be null.

By default, the successfully generated derivedKey will be passed to the callback as a Buffer. This behavior is deprecated, please specify a digest explicitly. The iterations argument must be a number set as high as possible. The higher the number of iterations, the more secure the derived key will be, but will take a longer amount of time to complete.

The salt should be as unique as possible. It is recommended that a salt is random and at least 16 bytes long. When passing strings for password or salt , please consider caveats when using strings as inputs to cryptographic APIs. This property, however, has been deprecated and use should be avoided. An array of supported digest functions can be retrieved using crypto. If an error occurs an Error will be thrown, otherwise the derived key will be returned as a Buffer. This property, however, is deprecated and use should be avoided.

Added string, ArrayBuffer, and CryptoKey as allowable key types. The oaepLabel can be an ArrayBuffer. The buffer can be a string or ArrayBuffer. Decrypts buffer with privateKey. If it is an object, the padding property can be passed. The passphrase can be an ArrayBuffer. Encrypts buffer with privateKey. The returned data can be decrypted using the corresponding public key, for example using crypto. Decrypts buffer with key. If key is not a KeyObject , this function behaves as if key had been passed to crypto.

Because RSA public keys can be derived from private keys, a private key may be passed instead of a public key. The oaepLabel and passphrase can be ArrayBuffers. Encrypts the content of buffer with key and returns a new Buffer with encrypted content. The returned data can be decrypted using the corresponding private key, for example using crypto. Generates cryptographically strong pseudorandom data. The size argument is a number indicating the number of bytes to generate. If a callback function is provided, the bytes are generated asynchronously and the callback function is invoked with two arguments: err and buf.

If an error occurs, err will be an Error object; otherwise it is null. The buf argument is a Buffer containing the generated bytes. If the callback function is not provided, the random bytes are generated synchronously and returned as a Buffer. An error will be thrown if there is a problem generating the bytes. This should normally never take longer than a few milliseconds. The only time when generating the random bytes may conceivably block for a longer period of time is right after boot, when the whole system is still low on entropy.

The asynchronous version of crypto. To minimize threadpool task length variation, partition large randomBytes requests when doing so as part of fulfilling a client request. Synchronous version of crypto. This function is similar to crypto. It also requires that a callback is passed in.

While this includes instances of Float32Array and Float64Array , this function should not be used to generate random floating-point numbers. To minimize threadpool task length variation, partition large randomFill requests when doing so as part of fulfilling a client request.

This implementation avoids modulo bias. The range max - min must be less than 2 If the callback function is not provided, the random integer is generated synchronously. The UUID is generated using a cryptographic pseudorandom number generator.

The cost , blockSize and parallelization option names have been added. Provides an asynchronous scrypt implementation. Scrypt is a password-based key derivation function that is designed to be expensive computationally and memory-wise in order to make brute-force attacks unrewarding. The callback function is called with two arguments: err and derivedKey. Provides a synchronous scrypt implementation. An exception is thrown when key derivation fails, otherwise the derived key is returned as a Buffer.

The flags is a bit field taking one of or a mix of the following flags defined in crypto. Throws an error if FIPS mode is not available. Calculates and returns the signature for data using the given private key and algorithm. If algorithm is null or undefined , then the algorithm is dependent upon the key type especially Ed and Ed This function is based on a constant-time algorithm.

Returns true if a is equal to b , without leaking timing information that would allow an attacker to guess one of the values. This is suitable for comparing HMAC digests or secret values like authentication cookies or capability urls. If at least one of a and b is a TypedArray with more than one byte per entry, such as Uint16Array , the result will be computed using the platform byte order.

Use of crypto. Care should be taken to ensure that the surrounding code does not introduce timing vulnerabilities. Verifies the given signature for data using the given key and algorithm. The signature argument is the previously calculated signature for the data. Because public keys can be derived from private keys, a private key or a public key may be passed for key. For historical reasons, many cryptographic APIs provided by Node. These instances include plaintexts, ciphertexts, symmetric keys, initialization vectors, passphrases, salts, authentication tags, and additional authenticated data.

Not all byte sequences are valid UTF-8 strings. Therefore, when a byte sequence of length n is derived from a string, its entropy is generally lower than the entropy of a random or pseudorandom n byte sequence. For example, no UTF-8 string will result in the byte sequence c0 af.
