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.
