AES interoperability

AES-GCM payload inspector

Paste a HashyTools AES v2 JSON payload or a legacy token. This inspector reads the structure locally; it never asks for or transmits your passphrase.

What the inspector validates

• Version, algorithm, PBKDF2 hash and work factor.
• Salt, IV and tag sizes required by the v2 format.
• Base64URL encoding and optional authenticated data.
• Legacy GCM/CBC tokens generated by prior HashyTools versions.
