rnp_op_sign

(PECL rnp >= 0.1.1)

rnp_op_sign — Perform signing operation on a binary data, return embedded signature(s)

説明

rnp_op_sign(
    RnpFFI $ffi,
    string $data,
    array $keys_fp,
    array $options = ?
): string|false

パラメータ

ffi
The FFI object returned by rnp_ffi_create().
data
Data to be signed.
keys_fp
Array with key fingerprints. At least one key must be provided. Keys should be present in ffi.
options
An associative array with options.
Key Data type 説明
"compression_alg" string Compression algorithm. Both "compression_alg" and "compression_level" must be set in order to enable data compression.
"compression_level" integer Compression level, 0-9. 0 disables compression.
"armor" boolean Enable ASCII-armored output. Disabled by default.
"hash" string Set hash algorithm used during signature calculation.
"creation_time" integer Set signature creation time in seconds since Jan, 1 1970 UTC. By default current time is used.
"expiration_time" integer Set signature expiration time in seconds since the creation time. 0 value is used to mark signature as non-expiring (default value).
"file_name" string Set input file name.Special value _CONSOLE may be used to mark message as 'for your eyes only', i.e. it should not be stored anywhere but only displayed to the receiver. Default is the empty string.
"file_mtime" integer Set input file modification date in seconds since Jan, 1 1970 UTC.

戻り値

Data with embedded signature(s) on success失敗した場合に false を返します.
