transform

Chain encode/decode steps and see the value at every arrow. Add steps from the dropdown. Flip between encode and decode with ⇄. Remove a step with ×.

When every step is reversible the chain is marked reversible and you can run it backwards in one click.

Try these:

• V NZ LBHE SNGURE → rot13 – Star Wars spoiler
• PNXR VF N YVR → rot13 – Portal
• REDRUM → reverse – The Shining
• SVOOL → atbash – Gravity Falls style
• TmV2ZXIgZ29ubmEg... → base64 decode – trust me
• VGhlcmUgaXMgbm8g... → base64 decode – 1999
• Hello → hex → sort – goes red at sort (irreversible)

Decode these (click ⇌ reverse pipeline to verify):

• CTF flag – 4-step decode
• Ovaltine – rot13 → base64 decode
• DEF CON 34 – reverse → hex decode
• Et tu, Brute – Caesar's own cipher

See Reversible Pipeline Transforms for the theory.
