# GPG Encrypt/Decrypt Scripts

Created 2026-02-04. Two utility scripts for symmetric GPG encryption with clipboard support.

## Scripts

### encryptfile

Location: `~/.local/bin/encryptfile`

Encrypts a file using symmetric GPG (password-based, no key required).

```bash
#!/bin/bash
# Encrypt a file with symmetric GPG (password-based)
# Usage: encryptfile <file>

if [ -z "$1" ]; then
    echo "Usage: encryptfile <file>"
    exit 1
fi

if [ ! -f "$1" ]; then
    echo "File not found: $1"
    exit 1
fi

gpg --symmetric --cipher-algo AES256 --armor -o "${1}.gpg" "$1" && \
    echo "Encrypted to ${1}.gpg" && \
    rm -i "$1"
```

### decryptfile

Location: `~/.local/bin/decryptfile`

Decrypts a GPG file and copies content to system clipboard. Supports both Wayland (wl-copy) and X11 (xclip).

```bash
#!/bin/bash
# Decrypt a GPG file to clipboard (symmetric)
# Usage: decryptfile <file.gpg>

if [ -z "$1" ]; then
    echo "Usage: decryptfile <file.gpg>"
    exit 1
fi

if [ ! -f "$1" ]; then
    echo "File not found: $1"
    exit 1
fi

# Decrypt and copy to clipboard
if command -v wl-copy &> /dev/null; then
    # Wayland
    gpg --decrypt "$1" 2>/dev/null | wl-copy
    echo "Decrypted content copied to clipboard (Wayland)"
elif command -v xclip &> /dev/null; then
    # X11
    gpg --decrypt "$1" 2>/dev/null | xclip -selection clipboard
    echo "Decrypted content copied to clipboard (X11)"
else
    echo "No clipboard tool found (need wl-copy or xclip)"
    echo "Decrypting to stdout instead:"
    gpg --decrypt "$1"
fi
```

## Usage

```bash
# Encrypt a file (prompts for password, deletes original)
encryptfile ~/.secrets/some-password

# Decrypt to clipboard (prompts for password)
decryptfile ~/.secrets/some-password.gpg
```

## Notes

- Uses AES256 cipher for encryption
- Outputs armored (ASCII) format for portability
- Prompts to delete original file after encryption
- Clipboard copy clears automatically on some systems
- Consider using `pass` (standard unix password manager) for more robust solution - wraps GPG with better UX

## Dependencies

- `gpg`
- `wl-copy` (Wayland) or `xclip` (X11) for clipboard support
