openssl_x509_fingerprint
Calculates the fingerprint, or digest, of a given X.509 certificate
Description
stringfalse openssl_x509_fingerprint(OpenSSLCertificatestring $certificate, string $digest_algo = "sha1", bool $binary = false)
Parameters
-
x509
-
See Key/Certificate parameters for a list of valid values.
-
digest_algo
-
The digest method or hash algorithm to use, e.g. "sha256", one of openssl_get_md_methods.
-
binary
-
When set to true, outputs raw binary data. false outputs lowercase hexits.
Return Values
Returns a string containing the calculated certificate fingerprint as lowercase hexits unless binary is set to true in which case the raw binary representation of the message digest is returned.
Returns false on failure.
