rnp_op_verify_detached — Verify detached signatures

rnp_op_verify_detached(RnpFFI $ffi, string $data, string $signature): array|false

An associative array with information about verification results 或者在失败时返回 false.

Key	Data type	说明
`"verification_status"`	string	Overall verification result, either "Success" string or appropriate error message. "Success" result is set when at least one signature is valid and successfully verified. Individual verification results for each signature can be checked in the "signatures" array.
`"file_name"`	string	File name.
`"file_mtime"`	integer	File modification time.
`"mode"`	string	Data protection (encryption) mode used in processed message. Currently defined values are "none", "cfb", "cfb-mdc", "aead-ocb", "aead-eax".
`"cipher"`	string	Symmetric cipher used for data encryption.
`"valid_integrity"`	boolean	`true` if message integrity protection was used (i.e. MDC or AEAD) and it was validated successfully.
`"signatures"`	array	An associative array describing each signature found. See description below.

"signatures" sub-array.

Key	Data type	说明
"verification_status"	string	Signature verification status, either "Success" string or appropriate error message.
"creation_time"	integer	Signature creation time in seconds since Jan, 1 1970 UTC.
"expiration_time"	integer	Signature expiration time in seconds since the creation time or 0 if signature never expires.
"hash"	string	Hash function algorithm used to calculate the signature.
"signing_key"	string	Fingerprint of the key used for signing. Could be "Not found" if corresponding public key is not loaded to the FFI object.
"signature_type"	string	Signature type. Currently defined values are: 'binary', 'text', 'standalone', 'certification (generic)', 'certification (persona)', 'certification (casual)', 'certification (positive)', 'subkey binding', 'primary key binding', 'direct', 'key revocation', 'subkey revocation', 'certification revocation', 'timestamp', 'uknown: 0..255'.
