byte[] |
decrypt_DES_ECB_PKCS5(byte[] ciphertext,
int offset,
int len,
byte[] secretKey)
Deprecated. use the getEncryptCipher and getDecryptCipher methods now that the java crypto API, and therefore the Cipher class, is standard and included in java 1.4 and higher. Using a returned Cipher object will be vastly more efficient than calling this method, which constructs a new Cipher every time. |
