Digital Signatures
This document contains technical details about algorithms for digital signatures for each PowerAuth Algorithm.
| PowerAuth Algorithm | Key type | DSA | JWS ID | |
|---|---|---|---|---|
| EC_P384_ML_L3 | EC | P-384 | ECDSA with SHA-384 | ES384 |
| ML-DSA | ML-DSA-65 | ML-DSA-65 | ML-DSA-65 | |
| EC_P384_ML_L5 | EC | P-384 | ECDSA with SHA-384 | ES384 |
| ML-DSA | ML-DSA-87 | ML-DSA-87 | ML-DSA-87 | |
| EC_P384 | EC | P-384 | ECDSA with SHA-384 | ES384 |
| LEGACY_P256 | EC | P-256 | ECDSA with SHA-256 | ES256 |
Be aware, that hybrid signatures are supported only in JWS specific API. The error is reported if you try to compute or validate hybrid signature in non-JWS API.
