Type Alias SshAlgorithm

SshAlgorithm:
    | { kind: "ed25519" }
    | { kind: "dsa" }
    | { kind: "rsa" }
    | { kind: "ecdsa"; curve: SshEcdsaCurve }

SSH key algorithm identifiers.

The six key algorithms ssh-key 0.6.7 generates and parses, and that the reference derives from a PrivateKeyBase:

Ed25519 (ssh-ed25519)
DSA (ssh-dss) — 1024-bit p, 160-bit q, SHA-1
RSA (ssh-rsa) — 2048-bit keys; sshsig signatures name their hash as rsa-sha2-256 / rsa-sha2-512 (RFC 8332)
ECDSA P-256 (ecdsa-sha2-nistp256) — SHA-256
ECDSA P-384 (ecdsa-sha2-nistp384) — SHA-384
ECDSA P-521 (ecdsa-sha2-nistp521) — SHA-512

Not supported: FIDO/U2F sk-* keys, opaque name@domain algorithms, encrypted private keys and *-cert-v01@openssh.com certificates.
