A password can also be specified as a hexadecimal key. <m/hex_key/ is a

specific algorithms can impose other restrictions).

<tag><label id="type-bytestring">bytestring</tag>
This is a sequences of arbitrary bytes. There are no ways to modify
bytestrings in filters. You can pass them between function, assign
them to variables of type <cf/bytestring/, print such values,
compare bytestings (<cf/=, !=/). Bytestring literals are written
in several ways:
A sequence of hexadecimal digit pairs, optionally colon-separated.
A bytestring specified this way must be at least 16 bytes (32 digits)
long: <cf/01:23:45:67:89:ab:cd:ef:01:23:45:67:89:ab:cd:ef/ or
<cf/0123456789abcdef0123456789abcdef/.
A sequence of hexadecimal digit pairs of any lengh (including zero)
with the <cf/hex:/ prefix. Colon separators can be inserted
arbitrarily between any bytes: <cf/hex:/, <cf/hex:1234/,
<cf/hex:1234:56:78/.
A bytestring can be made from a hex string using <cf/from_hex()/
function. Source strings can use any number of colons, hyphens and
spaces as byte separators: <cf/from_hex(" 1234 56:78 ab-cd-ef ")/.

Custom option definitions allow to define an arbitrary option to
advertise. You need to specify the option type number and the binary
