ML-DSA Public Key Bytes

Serializes an ML-DSA public key into bytes.

Source library: cryptography

Overview

This node extracts the public key from an ML-DSA private key and serializes it into a byte string. The resulting public key bytes can be shared with others, as public keys are not secret. They are used to verify signatures made by the corresponding private key.

Parameters

• sig_alg: The ML-DSA parameter set (ML-DSA-44, ML-DSA-65, or ML-DSA-87).
• key_source: How to obtain the private key.
  • From Private Bytes: Uses a previously serialized private key.
  • From Loaded Key: Uses a private key object passed from another node.
• encoding: The encoding format for the public key (PEM, DER, or Raw).
• formatting: The key format (SubjectPublicKeyInfo or Raw).
• private_bytes: (Optional) The serialized private key bytes (BYTESLIKE). Required when key_source is "From Private Bytes".
• private_key: (Optional) A loaded private key object (KEYOBJ). Required when key_source is "From Loaded Key".

Outputs

• public_bytes: The serialized public key as a BYTESLIKE object.
• public_key: The public key object (KEYOBJ), which can be passed to verification nodes.

Additional Considerations

• Public keys are not secret and can be freely distributed. They are used only for verification.
• The Raw format produces the smallest representation but may be less interoperable with other systems.
