Functions

func BrZip

func BrZip(data []byte, quality int) ([]byte, error)

BR 压缩 压缩数据

func BrZipFile

func BrZipFile(src, dst string, quality int) error

func Compress

func Compress(body []byte, compressMethod string, compressType string) (bool, []byte, error)

func GZip

func GZip(data []byte) ([]byte, error)

func GZipFile

func GZipFile(src, dst string) error

func GoDataAesCTRTransformDecode

func GoDataAesCTRTransformDecode(data []byte, aesKey []byte, aesIv []byte, compressMethod string) ([]byte, error)

func GoDataAesCTRTransformEncode

func GoDataAesCTRTransformEncode(data []byte, aesKey []byte, aesIv []byte, compressMethod string) ([]byte, error)

加密和解密AesCtr(zip(data))

compressMethod 空时不会压缩和解压

func GoDataDecrypt

func GoDataDecrypt(data []byte, AesKey []byte, compressMethod string) ([]byte, error)

解密：

1. 先取前16个字节，作为AES的IV

2. 取剩余的字节解密

3. 取前8个字节，作为时间戳

4. 取剩余的字节

5. 解压data(如果有压缩)

func GoDataEncrypt

func GoDataEncrypt(data []byte, AesKey []byte, compressMethod string) ([]byte, error)

AesIv 动态生成 (aes(time+zip(data)))

1. 先时间戳 time

2. 生成16位随机IV

3. 压缩data(如果有压缩) zip(data)

4. 加密data： aes(time+zip(data))

5. 拼接iv+encryptData

func UnBrZip

func UnBrZip(compressedData []byte) ([]byte, error)

解压数据

func UnBrZipFile

func UnBrZipFile(src, dst string) error

func UnGZip

func UnGZip(compressedData []byte) ([]byte, error)

func UnGZipFile

func UnGZipFile(src, dst string) error
