openssl_pkcs7_verify — Verifies the signature of an S/MIME signed message

Опис

openssl_pkcs7_verify(
    string $input_filename,
    int $flags,
    ?string $signers_certificates_filename = null,
    array $ca_info = [],
    ?string $untrusted_certificates_filename = null,

    ?string $output_filename = null
): bool|int

openssl_pkcs7_verify() reads the S/MIME message contained in the given file and examines the digital signature.

Параметри

input_filename

Path to the message.

flags

flags can be used to affect how the signature is verified - see PKCS7 constants for more information.

signers_certificates_filename

If the signers_certificates_filename is specified, it should be a string holding the name of a file into which the certificates of the persons that signed the messages will be stored in PEM format.

ca_info

If the ca_info is specified, it should hold information about the trusted CA certificates to use in the verification process - see certificate verification for more information about this parameter.

untrusted_certificates_filename

If the untrusted_certificates_filename is specified, it is the filename of a file containing a bunch of certificates to use as untrusted CAs.

content

You can specify a filename with content that will be filled with the verified data, but with the signature information stripped.

output_filename

Значення, що повертаються

Returns true if the signature is verified, false if it is not correct (the message has been tampered with, or the signing certificate is invalid), or -1 on error.
