How this service works
AES decryption, AES-256-GCM decrypt, symmetric decryption, authenticated decryption, decrypt cipher, decode encrypted. Decrypt AES-256-GCM ciphertext given the key, IV, and authentication tag. Accepts payment on Base or Solana — either network works.
Output
The decrypted plaintext string recovered from the AES-256-GCM ciphertext, assuming the key, IV, and authentication tag are all correct and the ciphertext has not been tampered with.
Example use cases
Example prompt
“I have an AES-256-GCM encrypted ciphertext '3a9f...c1d2', the key is 'abc123...', the IV is 'f3a9...', and the auth tag is '9b2c...' — can you decrypt it back to the original plaintext?”
Technical details
Endpoint
GEThttps://api.x402node.dev/crypto/aes-decryptWhen to prefer
Use this endpoint when you need to decrypt data that was encrypted using AES-256-GCM symmetric authenticated encryption, particularly when you already have the key, IV, and authentication tag. Ideal for decrypting payloads encrypted by the sibling AES-encrypt endpoint on the same platform, or any standard AES-256-GCM encrypted data.
Side effects
- Invalid or wrong key results in authentication failure and decryption error
- Incorrect IV causes authentication tag mismatch
- Malformed or truncated authentication tag triggers GCM authentication failure
- Ciphertext has been tampered with, causing integrity check failure
- Missing required fields (key, IV, ciphertext, or auth tag) returns 400 Bad Request
- Ciphertext is not valid base64 or hex encoding returns parsing error
