EdDSA Public Key Bytes

Serializes an EdDSA public key into bytes.

Source library: cryptography

Overview

This node extracts the public key from an EdDSA 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

• key_type: The EdDSA curve (Ed25519 or Ed448).
• key_source: How to obtain the private key.
  • From Loaded Key: Uses a private key object passed from another node.
  • From Private Bytes: Uses a previously serialized private key.
• encoding: The encoding format for the public key. Options: PEM, DER, Raw.
• formatting: The key format. Options: SubjectPublicKeyInfo (standard), Raw (raw key material).
• private_key: (Optional) The serialized private key bytes (BYTESLIKE). Required when key_source is "From Private Bytes".
• serialized_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.
