rnp_op_generate_key — Generate key
$ffi,$userid,$key_alg,$sub_alg = ?,$options = ?
ffiThe FFI object returned by rnp_ffi_create.
useridPGP User ID - text that is intended to represent the name and email address of the key holder.
key_algPrimary key algorithm (i.e. 'RSA', 'DSA', etc).
sub_algSubkey algorithm. If not set, subkey will not be generated.
optionsAn 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. |
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().
