Summary

Incorrect Length Encoding on KDF Export

Details

Passing values length > 65535 to Context::export produces output that disagrees with the RFC 9180 label encoding. In particular the length value is cast to u16 truncating any value exceeding 65535.

Impact

Applications that use hpke-rs to export very large secrets would experience interoperability issues with other applications that use a correct implementation to export very large secrets.

Mitigation

Starting with version 0.6.0, an error will be returned when attempting to call Context::export with an output length > 65535.
