Groovy crypt library
This Groovy crypt implementation of the crypt(3)
function provided in the GNU C library (glibc) was derived from crypt4j by Carl Harris https://github.com/soulwing/crypt4j
This implementation supports the MD5, SHA, SHA-256, and SHA-512 variants. Additionally, it supports legacy DES and HMAC.
It is useful for LDAP passwords or secure cookie handling.
Usage
void testHMAC() { String s = "Hello World" String secret = "secret" String code = CryptUtil.hmac(s, secret, "HmacSHA1") assertEquals("858da8837b87f04b052c0f6e954c3f7bbe081164", code) }
void testSHA() { String plaintext = 'geheim' String code = CryptUtil.sha(plaintext) assertEquals('SHA algorithm', '{sha}kGByAB793z4R5tK1eC9Hd/4Dhzk=', code) }
void testSSHA256() { String plaintext = 'geheim' byte[] salt = "467dd5b71e8d0f9e".decodeHex() String code = CryptUtil.ssha256(plaintext, salt) assertEquals('test SSHA-256 method', '{ssha256}9yT5rYItjXK+mY8sKNBcKsKSnlY6ysTg8wbDVmAguTFGfdW3Ho0Png==', code) }
void testSSHA512() { String plaintext = 'geheim' byte[] salt = "3c68f1f47f41d82f".decodeHex() String code = CryptUtil.ssha512(plaintext, salt) assertEquals('test SSHA-512 method', '{ssha512}jeWuCXRjsvKh/vK548GP9ZCs4q9Sh1u700C8eONyV+EL/P810C8vlx9Eu4vRjHq/TDoGW8FE1l/P2KG3w9lHITxo8fR/Qdgv', code) }
