(Go) RSA Encrypt and OpenSSL Decrypt
Demonstrates how to use Chilkat to RSA encrypt, and then use OpenSSL to decrypt. Note: This example requires Chilkat v11.0.0 or greater.
success := false
// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
rsa := Rsa_Ref.html">chilkat.NewRsa()
privKey := PrivateKey_Ref.html">chilkat.NewPrivateKey()
success = rsa.GenKey(2048,privKey)
success = privKey.SavePkcs8PemFile("qa_output/privKey.pem")
pubKey := PublicKey_Ref.html">chilkat.NewPublicKey()
privKey.ToPublicKey(pubKey)
rsa.SetEncodingMode("base64")
plainText := "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz01234567890"
bUsePrivateKey := false
rsa.UsePublicKey(pubKey)
encryptedStr := rsa.EncryptStringENC(plainText,bUsePrivateKey)
bd := BinData_Ref.html">chilkat.NewBinData()
bd.AppendEncoded(*encryptedStr,"base64")
success = bd.WriteFile("qa_output/enc.dat")
// The OpenSSL command to decrypt is:
// openssl pkeyutl -in enc.dat -inkey privKey.pem -keyform PEM -pkeyopt rsa_padding_mode:pkcs1 -decrypt
fmt.Println("OK")
rsa.DisposeRsa()
privKey.DisposePrivateKey()
pubKey.DisposePublicKey()
bd.DisposeBinData()
