RFC 3394 AES Key Wrap / Unwrap Integrity Verifier
x402
RFC 3394 AES Key Wrap / Unwrap Integrity Verifier is a paid API for AI agents from detect.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-11-01).
Performs and verifies RFC 3394 six-pass AES Key Wrap and Key Unwrap operations, including integrity checking and tampered-ciphertext rejection, given a Key Encryption Key and plaintext or wrapped key material in hex.

How this service works
A cryptographic-format conformance agent needs exact RFC3394 wrapped bytes and inverse integrity behavior from complete supplied public synthetic byte arrays, including rejection of tampered wraps without releasing plaintext. A raw AES block, CBC/CTR mode, HMAC or key-format validator does not implement the six-pass key-wrap transform.
Output
Returns the result of the RFC 3394 AES Key Wrap or Unwrap operation: the output key material as a hex string (or null on integrity failure), and a boolean indicating whether the integrity check passed. For unwrap operations on tampered input, the integrity flag is false and the plaintext is not released.
Example use cases
Key escrow wrap before storage
“I need to wrap this 256-bit session key (hex: 000102030405060708090a0b0c0d0e0fdeadbeefcafebabe0102030405060708) with my 256-bit KEK (hex: 6030a4f0b7e7ee2b1d3cf07b5e2e2a3c4f5a6b7c8d9e0f1a2b3c4d5e6f7a8b9c) using RFC 3394 — give me the wrapped bytes and confirm integrity is valid.”
Detect tampered wrapped key material
“I have a wrapped key blob that I suspect has been tampered with. Can you try to unwrap it using RFC 3394 with my KEK (hex: 0102030405060708090a0b0c0d0e0f10) and tell me whether the integrity check fails — the wrapped data hex is 1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f?”
Conformance test RFC 3394 wrap output
“Run the RFC 3394 wrap operation on plaintext key hex 00112233445566778899aabbccddeeff with KEK hex 000102030405060708090a0b0c0d0e0f and verify the six-pass transform produces the expected result hex 1fa68b0a8112b447aef34bd8fb5a7b829d3e862371d2cfe5 with integrity_valid true.”

Endpoint
POSThttps://detect.halowerk.com/v1/F-B-NIGHT-FINITE-STRUCTURES/rfc3394-complete-aes-key-wrap-unwrap-integrity?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need strict RFC 3394 conformance for the six-pass AES Key Wrap algorithm — including byte-exact output and real integrity verification that rejects tampered ciphertext without releasing plaintext. It is not a substitute for generic AES-CBC/CTR encryption, HMAC, or key-format parsing: use it specifically when the RFC 3394 key wrap transform and its built-in integrity envelope are required.
Side effects
- Tampered or corrupted wrapped key causes integrity check failure and null result_hex
- KEK hex does not match required 128/192/256-bit length pattern (32/48/64 hex chars) — input rejected
- data_hex does not conform to required minimum length or 8-byte block alignment pattern — rejected
- Mismatched operation and data length (e.g. wrap data too short, unwrap data missing ICV block)
- Malformed hex strings (odd length, non-hex characters) cause input validation errors
- Network or service timeout with no result returned
