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
AesDecryptRaw decrypt original `data` with `key` and initializer vector `iv` iv should have at least `aes.BlockSize` length.
AesEncryptRaw encrypt original `data` with `key` and initializer vector `iv` iv should have at least `aes.BlockSize` length.
BCryptHash encrypt original password with bcryptCost to encrypted data, then store encrypted data into database.
BCryptValidate validate password and encryptedData retrieved from database.
SetBCryptCost set global bcrypt cost, and after, all encrypt operation use this call before changed again.
# Constants
aes key size, 256 bit.
