Module ssh 

SSH cryptographic operations: key parsing, SSHSIG creation, and wire-format encoding.

Structs

SecureSeed

Zeroize-on-drop wrapper for a raw 32-byte signing seed.

Enums

CryptoError

Errors from SSH key construction, signing, and encoding operations.

Functions

build_ed25519_pkcs8_v2_from_seed

Build a PKCS#8 v2 DER document from a seed, deriving the public key internally.

construct_sshsig_pem

Construct the final SSHSIG PEM from a public key, curve, and raw signature.

construct_sshsig_signed_data

Construct the data blob that SSHSIG signs (the “message to sign”).

create_sshsig

Create an SSHSIG signature and return it as a PEM-armored string.

encode_mpint_for_agent

Encode a big integer for the SSH agent add_identity wire format.

encode_ssh_pubkey

Encode a public key in SSH wire format.

encode_ssh_signature

Encode a raw signature in SSH wire format.

extract_pubkey_from_key_bytes

Extract the 32-byte Ed25519 public key from key bytes.

extract_seed_from_pkcs8

Extract an Ed25519 seed from PKCS#8 key bytes.
