Openssl encryption

A functions wrapping of OpenSSL library for symmetric and asymmetric encryption and decryption

Installation

The only requirement is the Go Programming Language

go get -u github.com/forgoer/openssl

Usage

AES

The length of the key can be 16/24/32 characters (128/192/256 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)) // 123456

DES

The length of the key must be 8 characters (64 bits).

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)
