XCrypt

提供了快速加解密的方法。

AES

package xcrypt
// 参数分别对应 要加密的数据， 密钥， 初始化向量
// 加密
func AesEncryptRaw(data []byte, key []byte, iv []byte) ([]byte, error)
// 解密
func AesDecryptRaw(data []byte, key []byte, iv []byte) ([]byte, error)

Bcrypt

bcrypt 提供了密码加密/验证相关的操作。

brcypt主要思想是拖慢破解的速度，在cost为10的情况下，加密要比md5慢上百万倍，对应的暴力破解也是如此。 在值域一定的情况下，破解越慢， 被破解的可能性越低，从而保护密码的安全。

package xcrypt
func SetCost(cost int) {}

func BCryptHash(password []byte) ([]byte, error) {}

func BCryptValidate(password []byte, encryptedData []byte) bool {}

Functions

func AesDecryptRaw

func AesDecryptRaw(data []byte, key []byte, iv []byte) ([]byte, error)

AesDecryptRaw decrypt original `data` with `key` and initializer vector `iv` iv should have at least `aes.BlockSize` length

func AesEncryptRaw

func AesEncryptRaw(data []byte, key []byte, iv []byte) ([]byte, error)

AesEncryptRaw encrypt original `data` with `key` and initializer vector `iv` iv should have at least `aes.BlockSize` length

func BCryptHash

func BCryptHash(password []byte) ([]byte, error)

BCryptHash encrypt original password with bcryptCost to encrypted data, then store encrypted data into database.

func BCryptValidate

func BCryptValidate(password []byte, encryptedData []byte) bool

BCryptValidate validate password and encryptedData retrieved from database.

func SetBCryptCost

func SetBCryptCost(cost int)

SetBCryptCost set global bcrypt cost, and after, all encrypt operation use this call before changed again
