2 * Quick & dirty crypto testing module.
3 *
4 * This will only exist until we have a better testing mechanism
5 * (e.g. a char device).

15 *
16 * 2007-11-13 Added GCM tests
17 * 2007-11-13 Added AEAD support
18 * 2007-11-06 Added SHA-224 and SHA-224-HMAC tests
19 * 2006-12-07 Added SHA384 HMAC and SHA512 HMAC tests
20 * 2004-08-09 Added cipher speed tests (Reyk Floeter <reyk@vantronix.net>)
21 * 2003-09-14 Rewritten by Kartikey Mahendra Bhatt
