Make hash functions return error value Some crypto libraries can return in these functions (e.g., if a specific hash function is disabled), so we better provide the caller a chance to check whether the call failed. The return values are not yet used anywhere, but they will be needed for future changes. 2009-08-16 07:06:00 -04:00			`* Copyright (c) 2003-2009, Jouni Malinen <j@w1.fi>`

Rename tls_prf() to tls_prf_sha1_md5() Prepare for multiple TLS PRF functions by renaming the SHA1+MD5 based TLS PRF function to more specific name and add tls_prf() within the internal TLS implementation as a wrapper for this for now.
