func AesCBCDecrypt ¶

func AesCBCDecrypt(cryted, key string) result.Result[string]

func AesCBCEncrypt ¶

func AesCBCEncrypt(orig, key string) result.Result[string]

func CheckPassword ¶

func CheckPassword(hash, password string) error

CheckPassword checks to see if the password matches the hashed password.

func Decrypt ¶

func Decrypt(ciphertext []byte, key *[32]byte) (plaintext []byte, err error)

Decrypt decrypts data using 256-bit AES-GCM. This both hides the content of the data and provides a check that it hasn't been altered. Expects input form nonce|ciphertext|tag where '|' indicates concatenation.

func Encrypt ¶

func Encrypt(plaintext []byte, key *[32]byte) (ciphertext []byte, err error)

Encrypt encrypts data using 256-bit AES-GCM. This both hides the content of the data and provides a check that it hasn't been altered. Output takes the form nonce|ciphertext|tag where '|' indicates concatenation.

func HashPassword ¶

func HashPassword(password string) result.Result[string]

func Hmac ¶

func Hmac(key, data string) string

Hmac key随意设置 data 要加密数据

func HmacSha256 ¶

func HmacSha256(key, data string) string

func PKCS7Padding ¶

func PKCS7Padding(ciphertext []byte, size int) []byte

PKCS7Padding 补码

func PKCS7UnPadding ¶

func PKCS7UnPadding(origData []byte) []byte

PKCS7UnPadding 去码

func SecureKey ¶

func SecureKey() *[32]byte

SecureKey generates a random 256-bit key for Encrypt() and Decrypt(). It panics if the source of randomness fails.

func SecureToken ¶

func SecureToken(lengths ...int) string

SecureToken create a new random token
