字符编码类型常量

Functions

func DeSkip32

func DeSkip32(key string, value uint32) (uint32, error)

DeSkip32 解密

func DecodeAESCBC

func DecodeAESCBC(data, key []byte) (contentBytes []byte, err error)

DecodeAESCBC aes-256-cbc AES/CBC/PKCS5Padding

AES_CBC加密解密的算法为: aes-256-cbc, iv初始向量为随机16位字符串, padding为PKCS5Padding, 常用于HTTP中, 过程如下: 1.客户端发送加密请求体 ---> 2.服务器接收请求体并解密 ---> 3.服务器处理请求,返回加密响应体 ---> 4.客户端接收响应体并解密

解密数据处理的流程为: 先将iv拼接加密的数据进行Base64解码, 然后按照aes-256-cbc用key和iv对数据进行解密, 最后对数据进行zlib 6 level解压 即 AES_CBC解密: base64解密 --> AES解密 --> 解压缩

func DecodeAESGCM

func DecodeAESGCM(data, key []byte) (contentBytes []byte, err error)

DecodeAESGCM aes-256-gcm AES/GCM/NoPadding

AES_GCM加密解密的算法为: aes-256-gcm, nonce为随机12位字符串, padding为NoPadding, 常用于HTTP中, 过程如下: 1.客户端发送加密请求体 ---> 2.服务器接收请求体并解密 ---> 3.服务器处理请求,返回加密响应体 ---> 4.客户端接收响应体并解密

解密数据处理的流程为: 先将nonce拼接加密的数据进行Base64解码, 然后按照aes-256-gcm用key和nonce对数据进行解密, 最后对数据进行zlib 6 level解压 即 AES_GCM解密: base64解密 --> AES解密 --> 解压缩

func EnSHA256

func EnSHA256(value string) string

EnSHA256 SHA256加密

func EnSkip32

func EnSkip32(key string, value uint32) (uint32, error)

EnSkip32 加密

func EncodeAESCBC

func EncodeAESCBC(data, key []byte) (base64ContentBytes []byte, err error)

EncodeAESCBC aes-256-cbc AES/CBC/PKCS5Padding

AES_CBC加密解密的算法为: aes-256-cbc, iv初始向量为随机16位字符串, padding为PKCS5Padding, 常用于HTTP中, 过程如下: 1.客户端发送加密请求体 ---> 2.服务器接收请求体并解密 ---> 3.服务器处理请求,返回加密响应体 ---> 4.客户端接收响应体并解密

加密数据处理的流程为: 先对数据进行zlib 6 level压缩, 然后按照aes-256-cbc用key和iv对数据进行加密, 最后对iv拼接加密的数据进行Base64编码 即 AES_CBC加密: 压缩 --> AES加密 --> base64加密

func EncodeAESGCM

func EncodeAESGCM(data, key []byte) (base64ContentBytes []byte, nonceBytes []byte, err error)

func EncodeMD5

func EncodeMD5(value string) string
