Troubleshooting

Wrong Password Error

  • AES: Password is incorrect
  • Try alternate passwords if you have multiple
  • Ensure CAPS LOCK is off

  • Check for extra spaces

  • PGP: Passphrase is incorrect

  • Enter the passphrase for your private key
  • Try again if you mistyped

File Not Found

  • Verify the file path is correct
  • Check file exists and is readable
  • Ensure path has no typos

Unsupported Format

  • File may not be encrypted with EncryptoCLI
  • Check file extension and format
  • Ensure file wasn't corrupted
  • Try with original encryption method

PGP Key Not Found

  • Ensure GPG is installed
  • Run gpg --list-secret-keys to see your private keys
  • Import recipient's public key if needed

Recovery Options

If you've forgotten a password or passphrase:

  • AES: No recovery option - password is unrecoverable
  • PGP: Can create new key pair, but previous encrypted files cannot be recovered

Always keep secure backups of: - PGP private keys - Passwords in a password manager - Passphrases in a secure location
