API Reference
  1. ANKASecure API – Enterprise Post-Quantum Cryptography
  2. Secure Streaming

Re-encrypt data (streaming).

post
https://{host}:{port}/api/v3/crypto/stream/reencrypt

Decrypts the incoming ciphertext using oldKid (from the JWE header)
and re-encrypts it on the fly with newKid (provided via query parameter).
Returns a new multipart/mixed response containing the JWE header and the re-encrypted ciphertext.
All key-selection metadata is returned in the single Crypto-Policy-Info response header.


Supports all key type combinations:

• SIMPLE → SIMPLE (single recipient → single recipient)

• SIMPLE → COMPOSITE (single recipient → multiple recipients)

• COMPOSITE → COMPOSITE (multiple recipients → multiple recipients)

• COMPOSITE → SIMPLE (multiple recipients → single recipient)

Query Params
string
required

Public-key kid for the new ciphertext.

string

Optional fallback kid to decrypt a JWE header that
contains no kid (legacy / unmanaged artefacts).

• Must reference a key already imported and flagged
decryptOnly.

• Do not send this parameter when the JWE header
already includes a kid – the request will be
rejected with HTTP 400.

Body Params
header
object
required

JWE header in General-JSON serialization.

• Managed flow – if recipients[0].header.kid
is present, that kid is used as the decryption key.

• Migration flow – when the header lacks a kid
(legacy ciphertext) the caller must supply
sourceKidOverride.

file
required

Original ciphertext envelope (binary).
