We had a process that ran for almost 3 years with no problems until last week.
We tried to generate an encrypted file and it successfully made it, but on decryption, it gave us this error:
It's not possible to decrypt this message because your keyring does not contain usable private key(s) corresponding to any of the above public key(s).
How can I fix this problem?
Also, After this error, we're trying now to add some Integrity Check for the encrypted files, so, is there any thing that I can do with pgp's .exe file(s) to do so? Or what else should I do with my code to make this thing work?
