rnp_op_generate_key

(PECL rnp >= 0.1.1)

rnp_op_generate_key — Generate key

说明

rnp_op_generate_key(
    RnpFFI $ffi,
    string $userid,
    string $key_alg,
    string $sub_alg = ?,
    array $options = ?
): string|false

参数

ffi

The FFI object returned by rnp_ffi_create.

userid

PGP User ID - text that is intended to represent the name and email address of the key holder.

key_alg

Primary key algorithm (i.e. 'RSA', 'DSA', etc).

sub_alg

Subkey algorithm. If not set, subkey will not be generated.

options

An associative array with options.

Key	Data type	说明
`"bits"`	integer	Primary key size in bits. Applicable only to RSA, DSA and El-Gamal keys.
`"hash"`	string	Hash algorithm used in self signature or subkey binding signature.
`"dsa_qbits"`	integer	Set size of a `q` parameter for DSA key. Note: appropriate default value will be set, depending on key bits. However you may override it if needed.
`"curve"`	string	Set the curve used for ECC key. Note: this is only applicable for ECDSA, ECDH and SM2 keys.
`"request_password"`	boolean	Enable requesting password via password provider. This password will be used for key encryption. Password provider callback function should be set in advance by calling rnp_ffi_set_pass_provider(). Note: this setting will be ignored if password was set via`"password"`
`"password"`	string	Set the password used to encrypt the secret key data.
`"expiration"`	integer	Set the key and subkey expiration time in seconds.
`"sub_bits"`	integer	Subkey size in bits. Applicable only to RSA, DSA and El-Gamal keys.
`"sub_hash"`	string	Hash algorithm used in subkey self signature or subkey binding signature.
`"sub_curve"`	string	Set the curve used for ECC subkey. Note: this is only applicable for ECDSA, ECDH and SM2 keys.

返回值

Fingerprint of the generated primary key 或者在失败时返回 false. This fingerprint can be used later to reference the key in sign and encrypt operations. The key data is stored in FFI memory context and can be saved using rnp_save_keys() or rnp_save_keys_to_path().
