(Chilkat2-Python) RSA Encrypt and OpenSSL Decrypt
Demonstrates how to use Chilkat to RSA encrypt, and then use OpenSSL to decrypt.
import chilkat2
# This requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.
rsa = chilkat2.Rsa()
success = rsa.GenerateKey(2048)
# privKey is a CkPrivateKey
privKey = rsa.ExportPrivateKeyObj()
success = privKey.SavePkcs8PemFile("qa_output/privKey.pem")
rsa.EncodingMode = "base64"
plainText = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz01234567890"
bUsePrivateKey = False
encryptedStr = rsa.EncryptStringENC(plainText,bUsePrivateKey)
bd = chilkat2.BinData()
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
print("OK")
