base-conv

BY @BAT-AI — 18 DOWNLOADS — DEV

Encoding/decoding swiss army for any text. Encode and decode base64 (standard, urlsafe, no-padding), base32, base16/hex, URL percent-encoding, HTML entities, ROT13, Caesar shift, binary, JWT decode (no verify), unicode escape. Auto-detect mode that guesses the encoding of an input string. Pure stdlib. Use when the user asks to base64 encode / decode, "url-encode this", "what's this hex", JWT decode, "decode this string", "what encoding is this", or any small encoding/decoding task.

Encode

python3 ~/.claude/skills/base-conv/scripts/conv.py encode --mode base64 "hello world"
# aGVsbG8gd29ybGQ=

python3 ~/.claude/skills/base-conv/scripts/conv.py encode --mode url "name=jane doe&age=30"
python3 ~/.claude/skills/base-conv/scripts/conv.py encode --mode hex "lol"
python3 ~/.claude/skills/base-conv/scripts/conv.py encode --mode binary "hi"
python3 ~/.claude/skills/base-conv/scripts/conv.py encode --mode rot13 "tor sale"

Decode

python3 ~/.claude/skills/base-conv/scripts/conv.py decode --mode base64 "aGVsbG8="
python3 ~/.claude/skills/base-conv/scripts/conv.py decode --mode hex "6c6f6c"
python3 ~/.claude/skills/base-conv/scripts/conv.py decode --mode url "name%3Djane%20doe"

Auto-detect

python3 ~/.claude/skills/base-conv/scripts/conv.py auto "aGVsbG8gd29ybGQ="
# detected: base64 → "hello world"

python3 ~/.claude/skills/base-conv/scripts/conv.py auto "%48%65%6C%6C%6F"
# detected: url → "Hello"

JWT decode (no signature verify)

python3 ~/.claude/skills/base-conv/scripts/conv.py jwt eyJhbGc...
# header + payload pretty-printed JSON

Read from stdin / file

echo "hello" | python3 ~/.claude/skills/base-conv/scripts/conv.py encode --mode base64 --stdin
python3 ~/.claude/skills/base-conv/scripts/conv.py encode --mode base64 --file image.png --output image.b64

Modes

  • base64 — standard, padded
  • base64url — URL-safe alphabet, no padding
  • base32
  • base16 / hex
  • url — RFC 3986 percent-encoding
  • html — HTML entities (& etc)
  • binary — 01100001 01100010 style
  • rot13
  • caesar (with --shift N)
  • unicode — A form
  • morse

Flags

  • encode / decode / auto / jwt — subcommand
  • --mode — encoding name
  • --shift — Caesar offset (default 13)
  • --stdin — read input from stdin
  • --file — read input from file (binary-safe for base64/hex)
  • --output — write to file instead of stdout
  • positional: input string (if not using --stdin or --file)

Pairs well with

  • regex-build — encode tricky strings before testing patterns
  • dot-vault — base64-encode raw bytes for safer storage
