Method Details

setKey

public static void setKey(String myKey)

encrypt

public static String encrypt(String strToEncrypt,
 String secret)

decrypt

public static String decrypt(String cipherText,
 String secret)

decrypt

Parameters:

cipherText - text to decrypt

secret - secret used to decrypt

Returns:

decrypted string

GenerateKeyAndIV

public static byte[][] GenerateKeyAndIV(int keyLength,
 int ivLength,
 int iterations,
 byte[] salt,
 byte[] password,
 MessageDigest md)

Generates a key and an initialization vector (IV) with the given salt and password.

This method is equivalent to OpenSSL's EVP_BytesToKey function (see https://github.com/openssl/openssl/blob/master/crypto/evp/evp_key.c). By default, OpenSSL uses a single iteration, MD5 as the algorithm and UTF-8 encoded password data.

Parameters:

keyLength - the length of the generated key (in bytes)

ivLength - the length of the generated IV (in bytes)

iterations - the number of digestion rounds

salt - the salt data (8 bytes of data or null)

password - the password data (optional)

md - the message digest algorithm to use

Returns:

an two-element array with the generated key and IV
