Functions

func Decode

func Decode(input string) (result string, err error)

Decode the input string using base64 decoding followed by gzip decompression, and returns the resulting string. If any error occurs during decoding or decompression, it returns an empty string and the corresponding error.

func Decrypt

func Decrypt(ciphertext string, key32 []byte) (plaintext string, err error)

Decrypt a variable-length string using AES-GCM

func DecryptFixed

func DecryptFixed(encodedCipherText string, random bool, fixKey []byte) (plaintext string, err error)

DecryptFixed decrypts an encrypted string using AES encryption.

func Encode

func Encode(input string) (result string, err error)

Encode the input string using gzip compression followed by base64 encoding, and returns the resulting encoded string.

func Encrypt

func Encrypt(plaintext string, key32 []byte) (ciphertext string, err error)

Encrypt a variable-length string using AES-GCM

func EncryptFixed

func EncryptFixed(plainText string, random bool, fixKey []byte) (encodedCipherText string, err error)

EncryptFixed encrypts a fixed-length string using AES encryption.

func PadPKCS7

func PadPKCS7(data []byte, blockSize int) []byte

func UnpadPKCS7

func UnpadPKCS7(data []byte) []byte
