func AppletDecrypt

func AppletDecrypt(sessionKey, encryptedData string, iv string) ([]byte, error)

微信小程序/头条小程序

解密小程序敏感信息: 对称解密使用的算法为 AES-128-CBC，数据采用PKCS#7填充。 对称解密的目标密文为 Base64_Decode(encryptedData)。 对称解密秘钥 aeskey = Base64_Decode(session_key), aeskey 是16字节。 对称解密算法初始向量 为Base64_Decode(iv)，其中iv由数据接口返回。

func Decrypt

func Decrypt(data []byte, key []byte) []byte

Decrypt the data with key. data is the bytes to be decrypted. key is the decrypted key. It is the same as the encrypt key.

func Encrypt

func Encrypt(data []byte, key []byte) []byte

Encrypt the data with key. data is the bytes to be encrypted. key is the encrypt key. It is the same as the decrypt key.

func FileExist

func FileExist(file string) error

FileExist return an error when a file does not exist

func GetUUID

func GetUUID() (string, error)
