sshkeys

sshkeys provides utilities for parsing and marshalling cryptographic keys used for SSH, in both cleartext and encrypted formats.

ssh.ParseRawPrivateKey only supports parsing a subset of the formats sshkeys supports, does not support parsing encrypted private keys, and does not support marshalling.

Supported Formats

• OpenSSH's PROTOCOL.key for RSA and ED25519 keys.
• OpenSSH version >= 7.6 using aes256-ctr encryption
• "Classic" PEM containing RSA (PKCS#1), DSA (OpenSSL), and ECDSA private keys.
