  34. def pbkdf2Sync(password: |[String, BufferLike], salt: |[String, BufferLike], iterations: Int, keylen: Int, digest: String): Buffer

    Provides a synchronous Password-Based Key Derivation Function 2 (PBKDF2) implementation.

    Provides a synchronous Password-Based Key Derivation Function 2 (PBKDF2) implementation. 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 an Error will be thrown, otherwise the derived key will be returned as a Buffer.

    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 also be as unique as possible. It is recommended that the salts are random and their lengths are greater than 16 bytes. See NIST SP 800-132 for details.

Deprecated Value Members

  1. val DEFAULT_ENCODING: String

    The default encoding to use for functions that can take either strings or buffers.

    The default encoding to use for functions that can take either strings or buffers. The default value is 'buffer', which makes methods default to Buffer objects.

    The crypto.DEFAULT_ENCODING mechanism is provided for backwards compatibility with legacy programs that expect 'binary' to be the default encoding.

    Annotations
    @deprecated
    Deprecated

    (Since version Node.js v10.0) New applications should expect the default to be 'buffer'.

  2. def createCipher(algorithm: String, password: |[Buffer, String]): Cipher

    Creates and returns a Cipher object that uses the given algorithm and password.

    Creates and returns a Cipher object that uses the given algorithm and password.

    algorithm

    The algorithm is dependent on OpenSSL, examples are 'aes192', etc. On recent OpenSSL releases, openssl list-cipher-algorithms will display the available cipher algorithms.

    password

    The password is used to derive the cipher key and initialization vector (IV). The value must be either a 'binary' encoded string or a Buffer.

    Annotations
    @deprecated
    Deprecated

    (Since version Node.js v10.0) Use crypto.createCipheriv() instead.

    Example:

    1. crypto.createCipher(algorithm, password)

  3. def createDecipher(algorithm: String, password: |[Buffer, String]): Decipher

    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 and password (key). The implementation of crypto.createDecipher() derives keys using the OpenSSL function EVP_BytesToKey with the digest algorithm set to MD5, one iteration, and no salt. 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.

    In line with OpenSSL's recommendation to use pbkdf2 instead of EVP_BytesToKey it is recommended that developers derive a key and IV on their own using crypto.pbkdf2() and to use crypto.createDecipheriv() to create the Decipher object.

    Annotations
    @deprecated
    Deprecated

    (Since version Node.js v10.0) Use crypto.createDecipheriv() instead.

    Example:

    1. crypto.createDecipher(algorithm, password)

  4. val fips: Boolean

    Property for checking and controlling whether a FIPS compliant crypto provider is currently in use.

    Property for checking and controlling whether a FIPS compliant crypto provider is currently in use. Setting to true requires a FIPS build of Node.js.

    Annotations
    @deprecated
    Deprecated

    (Since version Node.js v10.0) Please use crypto.setFips() and crypto.getFips() instead.
