(PHP 5.6, PHP 7)

Calculates the fingerprint, or digest, of a given X.509 certificate

bool openssl_x509_fingerprint ( mixed $x509 [, string $hash_algorithm = "sha1" [, bool $raw_output = FALSE ]] )

openssl_x509_fingerprint() returns the digest of x509 as a string.

Parameters:

x509

See Key/Certificate parameters for a list of valid values.

hash_algorithm

The hash algorithm to use, e.g. "md5" or "sha1"
