Functions

func AESCBCDecrypt

func AESCBCDecrypt(dst, cipherText, key, iv []byte) (int, error)

AESCBCDecrypt decrypts encryptText with key and iv key length must be 16, 24 or 32 bytes to select AES-128, AES-192 or AES-256. iv length must be 16 bytes, iv should be random to ensure safety dst could reuse encryptText memory

func AESCBCDecryptLen

func AESCBCDecryptLen[T typez.StrOrBytes](cipherText T) int

AESCBCDecryptLen returns the length of the decrypted data

func AESCBCEncrypt

func AESCBCEncrypt(dst, plainText, key, iv []byte) error

AESCBCEncrypt encrypts plainText with key and iv key length must be 16, 24 or 32 bytes to select AES-128, AES-192 or AES-256. iv length must be 16 bytes, iv should be random to ensure safety plainText could pre grow padding length, so dst could reuse plainText memory

func AESCBCEncryptLen

func AESCBCEncryptLen[T typez.StrOrBytes](plainText T) int

AESCBCEncryptLen returns the length of the encrypted data

func AESGCMDecrypt

func AESGCMDecrypt(dst, cipherText, key, nonce, additionalData []byte) error

AESGCMDecrypt decrypts encryptText with key and additionalData key length must be 16, 24 or 32 bytes to select AES-128, AES-192 or AES-256. dst could reuse encryptText memory, like encryptText[:AESGCMDecryptLen(encryptText)]

func AESGCMDecryptLen

func AESGCMDecryptLen[T typez.StrOrBytes](cipherText T) int

AESGCMDecryptLen returns the length of the decrypted data

func AESGCMEncrypt

func AESGCMEncrypt(dst, plainText, key, nonce, additionalData []byte) error

AESGCMEncrypt encrypts plainText with key and additionalData key length must be 16, 24 or 32 bytes to select AES-128, AES-192 or AES-256. plainText could pre grow tagSize(default 16) so dst could reuse plainText memory

func AESGCMEncryptLen

func AESGCMEncryptLen[T typez.StrOrBytes](plainText T) int

AESGCMEncryptLen returns the length of the encrypted data

func Decrypt

func Decrypt[T, E typez.StrOrBytes](cipherText T, secret E) ([]byte, error)

func DecryptStreamTo

func DecryptStreamTo[E typez.StrOrBytes](out io.Writer, stream io.Reader, secret E) error

DecryptStreamTo decrypts stream to out with secret

func Encrypt

func Encrypt[T, E typez.StrOrBytes](plainText T, secret E) ([]byte, error)

Encrypt encrypts plainText with secret (openssl aes-256-cbc implementation).

func EncryptStreamTo

func EncryptStreamTo[E typez.StrOrBytes](out io.Writer, stream io.Reader, secret E) error

EncryptStreamTo encrypts stream to out with secret

func GCMDecrypt

PKCS7Padding adds padding to the input data according to the PKCS#7 standard

func PKCS7UnPadding

func PKCS7UnPadding(data []byte, blockSize int) ([]byte, error)

PKCS7UnPadding removes padding from the input data according to the PKCS#7 standard
