myPKEModule.Decrypt(encryptedData);
| myPKEModule | The name of the Public Key Encryption From LFN (Logical FileName) module structure |
| encryptedData | The data to decrypt in DATA format |
| Return: | Decrypted contents in DATA format |
The Decrypt function decrypts the given encryptedData, using the options specified in the Public Key Encryption From LFN module definition. You can only decrypt data that was encrypted by the Standard Library's Encrypt method.
Example:
IMPORT Std;
PublicKeyFile := '~Examples::certificates::public::pubkey.pem';
PrivateKeyFile:= '~Examples::certificates::private::privkey.pem';
//You can restrict access using file scope security
//on the ~Examples::certificates::private scope
pubKey := RECORD
STRING Key;
