Function CoderSigner

agent/agentssh/agentssh.go:1386–1394

CoderSigner generates a deterministic SSH signer based on the provided seed. It uses RSA with a key size of 2048 bits.

(seed int64)

// CoderSigner generates a deterministic SSH signer based on the provided seed.
// It uses RSA with a key size of 2048 bits.

	// The agent needs to authenticate with coderd to SSH,
	// so SSH authentication doesn't improve security.

	coderSigner, err := gossh.NewSignerFromKey(coderHostKey)
