key_fingerprint_digest()

asciichat_error_t key_fingerprint_digest	(	const uint8_t	public_key[ED25519_PUBLIC_KEY_SIZE],
		uint8_t	digest[32] )

SHA-256 of the 32 public-key bytes, independent of key source or encoding.

References ED25519_PUBLIC_KEY_SIZE, and KEYMASK_DIGEST_SIZE.

keymask_render()

asciichat_error_t keymask_render	(	const uint8_t	digest[32],
		bool	unicode,
		char *	out,
		size_t	size )

Keymask v2: domain-separated constructed mask from the public-key digest. ASCII and UTF-8 represent the same geometry. No terminal I/O or allocations. This is a recognition aid; exact and perceptual collisions are possible.
