I have a client who wanted me to encrypt a file and send it to them to decrypt. I have their public key imported to Kleopatra.
But when i send the encrypted file to them, it says decryption failed as the file is encrypted with a key that is not recognized.
I realized that on the sub key details, the key ID for signing and encrypting are different.
Is there a way to make it the same key ID for signing and encrypting?
