  6. 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.

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

    Example:

    1. crypto.createCipher(algorithm, password)

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

    Example:

    1. crypto.createDecipher(algorithm, password)

  18. def createHash(algorithm: String): Hash

    Creates and returns a Hash object that can be used to generate hash digests using the given algorithm.

    Creates and returns a Hash object that can be used to generate hash digests using the given algorithm.

    The algorithm is dependent on the available algorithms supported by the version of OpenSSL on the platform. Examples are 'sha256', 'sha512', etc. On recent releases of OpenSSL, openssl list-message-digest-algorithms will display the available digest algorithms.

    algorithm

    the given algorithm (e.g. 'sha256', 'sha512')

  19. def createHmac(algorithm: String, key: String): Hmac

    Creates and returns an Hmac object that uses the given algorithm and key.

    Creates and returns an Hmac object that uses the given algorithm and key.

    The algorithm is dependent on the available algorithms supported by the version of OpenSSL on the platform. Examples are 'sha256', 'sha512', etc. On recent releases of OpenSSL, openssl list-message-digest-algorithms will display the available digest algorithms.

    algorithm

    the given algorithm (e.g. 'sha256', 'sha512')

    key

    The key is the HMAC key used to generate the cryptographic HMAC hash.

  20. def createSign(algorithm: String): Sign

    Creates and returns a Sign object that uses the given algorithm.

    Creates and returns a Sign object that uses the given algorithm. On recent OpenSSL releases, openssl list-public-key-algorithms will display the available signing algorithms. One example is 'RSA-SHA256'.

    algorithm

    the given algorithm (e.g. 'RSA-SHA256')

  21. def createVerify(algorithm: String): Verify

    Creates and returns a Verify object that uses the given algorithm.

    Creates and returns a Verify object that uses the given algorithm. On recent OpenSSL releases, openssl list-public-key-algorithms will display the available signing algorithms. One example is 'RSA-SHA256'.

    algorithm

    the given algorithm (e.g. 'RSA-SHA256')
