Functions
int	host_random (uint8_t *buf, size_t len)
	Fill buf with hardware-RNG bytes; may fall back to PRNG.
int	host_random_strict (uint8_t *buf, size_t len)
	Fill buf with hardware-RNG bytes only; fails without TRNG.
int	host_sha256 (const uint8_t *data, size_t len, uint8_t out[32])
	SHA-256 hash of data into the 32-byte out.
int	host_hmac_sha256 (const uint8_t *key, size_t klen, const uint8_t *data, size_t dlen, uint8_t out[32])
	HMAC-SHA-256 of data under key into the 32-byte out.
int	host_aes_gcm_encrypt (const uint8_t *key, const uint8_t *iv, const uint8_t *aad, size_t aad_len, const uint8_t *pt, size_t pt_len, uint8_t *ct, uint8_t tag[16])
	AES-256-GCM encrypt.
int	host_aes_gcm_decrypt (const uint8_t *key, const uint8_t *iv, const uint8_t *aad, size_t aad_len, const uint8_t *ct, size_t ct_len, const uint8_t tag[16], uint8_t *pt)
	AES-256-GCM decrypt and verify.
int	host_base32_encode (const uint8_t *in, size_t in_len, char *out, size_t out_size)
	Base32-encode in into NUL-terminated out.
int	host_base32_decode (const char *in, size_t in_len, uint8_t *out, size_t out_size)
	Base32-decode in into raw bytes in out.
int	host_base64_encode (const uint8_t *in, size_t in_len, char *out, size_t out_size)
	Base64-encode in into NUL-terminated out.
int	host_base64_decode (const char *in, size_t in_len, uint8_t *out, size_t out_size)
	Base64-decode in into raw bytes in out.
int	host_hex_encode (const uint8_t *in, size_t in_len, char *out, size_t out_size)
	Lowercase-hex-encode in into NUL-terminated out.
int	host_hex_decode (const char *in, size_t in_len, uint8_t *out, size_t out_size)
	Hex-decode in (case-insensitive) into raw bytes in out.
