Calculates the fingerprint, or digest, of a given X.509 certificate
Description
bool openssl_x509_fingerprint
( mixed $x509
[, string $hash_algorithm
= "sha1"
[, bool $raw_output
= FALSE
]] )
Parameters
-
x509
-
See Key/Certificate parameters for a list of valid values.
-
hash_algorithm
-
The hash algorithm to use, e.g. "md5" or "sha1"
-
raw_output
-
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 raw_output
is set to TRUE
in which case the raw binary representation of the message digest is returned.
Returns FALSE
on failure.
