SHA256 and friends.

[Dirk-Willem van Gulik]

Where can I find the proper version of below — to do things like

        apr_crypto_hash_t * sha256_ctx = apr_crypto_sha256_new(pool); 

        apr_hash(sha256_ctx, …...

? Or was this abstracting in apr_random of the hash something which was never 
completed (nor had its MD2, MD5 and friends folded in) ?

Dw.
