The manual is not constistent at this point. On one hand, it describes the return as digest/fingerprint of a cert, on the other hand it says:
bool openssl_x509_fingerprint( … )
On PHP 5.6.5, I only get the bool return (1 or 0).
openssl_x509_fingerprint
(PHP 5 >= 5.6.0, PHP 7)
openssl_x509_fingerprint — Calculates the fingerprint, or digest, of a given X.509 certificate
Descrierea
openssl_x509_fingerprint

$x509
[, string $hash_algorithm = "sha1"
[, bool $raw_output = false
]] ) : string
openssl_x509_fingerprint() returns the digest of
x509 as a string.

When set to
true, outputs raw binary data.falseoutputs lowercase hexits.
Valorile întoarse
