GoCrypto使用说明

特别说明

based on GoRSA, GoCrypt Optimized the following points for packaging:

• Optimization of public and private keys requires registration and initialization in advance.
• The encryption machine does not perform base64 processing, and avoids secondary encapsulation of base64 during cross-program transfer or storage
• The incoming return uses the string type uniformly to avoid conversion trouble
• Supports RSAWithSHA1 and RSAWithSHA256 signature verification algorithms

此版本新增了AES、DES、3DES、HMAC、HASH等常见加/解密及hash获取方式，结构作了些调整，由之前的版本更新到此版本时一定要注意引用方法包名的变化。 AES/DES块加密时，填充默认采用PKCS7 padding( 如果块大小为64 位（8字节）时，此时PKCS7与PKCS5结果一致).

get & import

go get -u -v github.com/houseme/gocrypto

使用方法

1.构建需要加解密的类型handle

    handleRSA := rsa.NewRSACrypt(secretInfo) // RSA
    handleDES := des.NewDESCrypt(key) // des
    handle3DES := des.NewTripleDESCrypt(key) // 3des
    handleAES := aes.NewAESCrypt(key) // aes
    handleHash := hash.NewHash(hashType) // common hash
    handleHMAC := hash.NewHMAC(hashType, key) // hmac

2.加密、解密、hash、hmac

（1）加密

加密指定字符串，并以指定编码格式输出结果

    encrypt, err := handle.Encrypt(src) // des/3des/aes

（2）解密

解密指定格式编码后的加密串，返回原字符串

    decrypt, err := handle.Decrypt(src) // des/3des/aes

（3）hash/hmac

哈希运算/密钥相关的哈希运算。

    handle.Get([]byte("123456"))// 输出[]byte
    handle.EncodeToString([]byte("123456"), gocrypto.HEX) // 输出为hex格式的字符串

RSA加密、解密、签名、验签

1.设置公私钥信息

secretInfo := rsa.RSASecret{
    PublicKey:          "MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAyoiAraTnAbCoqGVOKugFDM2/ms2szXmb3zTOU3ByicH/XPZqy7Eougbs8OQQIoNW4xKw8PNyWf0lfr90qBfPj27INn6N7umVmbHCNCKkQ4frPn46xesw1ywtc2GhOEzZlC8ajlnzBUkj5FJZcrNjXfFmfsQcFQP0g/o/3CAUpk1BXFXt7eZsaYdyn0m7fMoyFt1wlF8egQeGYYE98vtKsvrII51HK8vOEf+5VXU4UZxGfvyzS3A8kuNEkKEh1n9mazjfPBT0KGSiOGh7Nugks+jjfswSgXRK/b2eP3fS7U625rbS798pKxnoS2E0Pgpzdk5fWoNgAlG/n2F9oI2/kQIDAQAB",

    return
}
fmt.Println("encrypt data :", encrypt)

（6）RSA公钥解密
