b64-clip

Base64 encode/decode with clipboard, zero dependencies.

Encode auth tokens, config values, certificate data, and more — result is automatically copied to your clipboard.

Install

pip install b64-clip

Or run directly (no install):

python3 b64_clip.py encode "hello world"

Usage

# Encode a string
b64-clip encode "hello world"
# Output: aGVsbG8gd29ybGQ=
# (also copied to clipboard)

# Decode a string
b64-clip decode "aGVsbG8gd29ybGQ="
# Output: hello world
# (also copied to clipboard)

# Encode a file
b64-clip encode --file cert.pem

# Decode a file
b64-clip decode --file encoded.txt

# Pipe from stdin
echo "test" | b64-clip encode

# URL-safe base64 decode
b64-clip decode --url-safe "PDw_Pz4-"

What it does

• Encode: Takes any input (string, file, or stdin) and outputs base64
• Decode: Takes base64 input and outputs the decoded plaintext
• Clipboard: Automatically copies the result to your clipboard on macOS, Linux (xclip/wl-copy), and Windows (clip.exe)
• Zero dependencies: Python stdlib only — no pip install needed at runtime

Requirements

• Python 3.11+
• For clipboard support: xclip on Linux (install with sudo apt install xclip), pbcopy on macOS (built-in), clip.exe on Windows (built-in)

Security
