myPKEModule := STD.Crypto.PublicKeyEncryption(pkAlgorithm, publicKeyFile, privateKeyFile, passphrase);
| myPKEModule | The name of the Public Key Encryption module structure |
| pkAlgorithm | The algorithm to use, as returned by SupportedPublicKeyAlgorithms() |
| publicKeyLFN / publicKeyBuff | The File Specification of the PEM formatted Public Key file |
| privateKeyLFN / privateKeyBuff | The File Specification of the PEM formatted Private Key file |
| passphrase | The passphrase to use for encryption, decryption, signing, verifying |
A Public Key Encryption module is defined in ECL. Subsequent function definitions use the options defined in the Public Key Encryption module to perform asymmetric encryption/decryption/digital signing/signature verification.
Example:
IMPORT STD;
privKeyFile := '/var/lib/HPCCSystems/myesp/test.key';
pubKeyFile := '/var/lib/HPCCSystems/myesp/test.key.pub';
//PKE Encryption module definition
myPKEModule := STD.Crypto.PublicKeyEncryption('RSA', pubKeyFile, privKeyFile,'');
DATA encrypted := myPKEModule.Encrypt((DATA)'The quick brown fox jumps over the lazy dog');
OUTPUT( (STRING)myPKEModule.Decrypt(encrypted) );
