SM2 Key Pair
Description
In the SM2 encryption algorithm, the private key and public key appear in pairs. The private key is a 64-bit hexadecimal string, and the public key is a 128-bit hexadecimal string, excluding the "04" prefix at the beginning. The public key is included in the private key and can be derived from the private key. We use the public key for encryption, the private key for decryption, the private key for signing, and the public key for verification.
Usage
sm2_gen_keypair()
sm2_pk_from_sk(private_key)
sm2_privkey_valid(private_key)
sm2_pubkey_valid(public_key)
sm2_keypair_from_pem_file(pem_file)
sm2_keypair_to_pem_file(private_key, pem_file)
sm2_pubkey_from_pem_file(pem_file)
sm2_pubkey_to_pem_file(public_key, pem_file)
Arguments
private_key |
a private key represented as a hexadecimal string |
public_key |
a public key represented as a hexadecimal string |
pem_file |
local pem file path |

sm2_pk_from_sk(keypair$private_key)
## check whether the private key is legal
sm2_privkey_valid(keypair$private_key)
## check whether the public key is legal
sm2_pubkey_valid(keypair$public_key)
