openssl_digest — Computes a digest
Computes a digest hash value for the given data using a given method, and returns a raw or binhex encoded string.
dataThe data.
digest_algoThe digest method to use, e.g. "sha256", see openssl_get_md_methods() for a list of available digest methods.
binary
Setting to true will return as raw output data, otherwise the return
value is binhex encoded.
Returns the digested hash value on success ou false em caso de falha.
Emits an E_WARNING level error if an unknown signature algorithm
is passed via the digest_algo parameter.
The second argument should be one of the values returned by openssl_get_md_methods() rather than hash_algos(). ‘Hash’ and ‘OpenSSL’ are independent extensions and support different selection of digest algorithms. Notably, Hash supports some non-cryptographic hashes like adler or crc.
