Constructor Detail

OpenSSLEncryptionScheme

public OpenSSLEncryptionScheme(SymmetricAlgorithm alg,
                               byte[] salt,
                               int keyBitLength)

Creates a new instance using the given parameters.

Parameters:

alg - Symmetric cipher algorithm used for encryption/decryption. The cipher is expected to be initialized with data required for use except, of course, the private key which will be generated from a password.

salt - Salt data for key generation function.

keyBitLength - Size of derived keys in bits.

OpenSSLEncryptionScheme

public OpenSSLEncryptionScheme(String algId,
                               byte[] iv)

Creates a new instance from an algorithm identifier string and salt data.

Parameters:

algId - Identifier describing the cipher used for key encryption. The form of the identifier follows the following convention:
$ALGORITHM-$MODE

iv - Cipher initialization vector data.
