This article shows you how to encrypt and decrypt AES, DES and 3DES in Golang. The content is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Functional wrapper of the Openssl encryption:OpenSSL library for symmetric and asymmetric encryption and decryption.

Install go get-u github.com/thinkoner/openssl usage AES

The length of the key can be 16-24-32 characters (128 ram 192 ram 256 bits).

AES-ECB:

Src: = byte ("123456") key: = [] byte ("1234567890123456") dst, _: = openssl.AesECBEncrypt (src, key, openssl.PKCS7_PADDING) fmt.Printf (base64.StdEncoding.EncodeToString (dst)) / / yXVUkR45PFz0UfpbDB8/ew==dst, _ = openssl.AesECBDecrypt (dst, key, openssl.PKCS7_PADDING) fmt.Println (string (dst)) / / 123456

AES-CBC:

Src: = byte ("123456") key: = [] byte ("1234567890123456") iv: = [] byte ("1234567890123456") dst, _: = openssl.AesCBCEncrypt (src, key, iv, openssl.PKCS7_PADDING) fmt.Println (base64.StdEncoding.EncodeToString (dst)) / / 1jdzWuniG6UMtoa3T6uNLA==dst, _ = openssl.AesCBCDecrypt (dst, key, iv, openssl.PKCS7_PADDING) fmt.Println (string (dst)) / / 123456DES

The key must be 8 characters (64 bits) long.

DES-ECB:

Openssl.DesECBEncrypt (src, key, openssl.PKCS7_PADDING) openssl.DesECBDecrypt (src, key, openssl.PKCS7_PADDING)

DES-CBC:

Openssl.DesCBCEncrypt (src, key, iv, openssl.PKCS7_PADDING) openssl.DesCBCDecrypt (src, key, iv, openssl.PKCS7_PADDING) 3DES

The length of the key must be 24 characters (192 bits).

3DES-ECB:

Openssl.Des3ECBEncrypt (src, key, openssl.PKCS7_PADDING) openssl.Des3ECBDecrypt (src, key, openssl.PKCS7_PADDING)

3DES-CBC:

Openssl.Des3CBCEncrypt (src, key, iv, openssl.PKCS7_PADDING) openssl.Des3CBCDecrypt (src, key, iv, openssl.PKCS7_PADDING) the above content is what AES, DES, 3DES encryption and decryption are like in Golang.
