[PATCH] apr-util hmac md5

[Sander Striker]

Hi,

This patch adds HMAC MD5 to apr-util.

Functions:

APU_DECLARE(apr_status_t) apr_hmac_md5_init(apr_hmac_md5_ctx_t *context,
                                            const unsigned char *key,
                                            apr_size_t keyLen);

APU_DECLARE(apr_status_t) apr_hmac_md5_update(apr_hmac_md5_ctx_t *context,
                                              const unsigned char *input,
                                              apr_size_t inputLen);

APU_DECLARE(apr_status_t) apr_hmac_md5_final(unsigned char
digest[MD5_DIGESTSIZE],
                                             apr_hmac_md5_ctx_t *context);

APU_DECLARE(apr_status_t) apr_hmac_md5(unsigned char digest[MD5_DIGESTSIZE],
                                       const unsigned char *key,
                                       apr_size_t keyLen,
                                       const unsigned char *input,
                                       apr_size_t inputLen);

The algorithm is pretty straightforward and I needed it anyway.
I used RFC2104 as a guide.

It probably needs some looking over. Also the doc comments are a bit
dense (I'm a bit to tired to come up with any good ones).

Thx,

Sander

PS. If someone is looking into MD5, maybe MD5_DIGESTSIZE can be changed to
APR_MD5_DIGESTSIZE, like in the md4 code (which has APR_MD4_DIGESTSIZE).
