lightning-makesecret -- Command for deriving pseudorandom key from HSM
=====================================================================
SYNOPSIS
--------
**makesecret** [*hex*] [*string*]
DESCRIPTION
-----------
doc: escape more naughty underscores The only time underscores aren't special in Markdown is when they appear in preformatted text. We have gotten away with not escaping underscores where an asterisk-enclosed span or the paragraph ends before the next underscore appears, but this is fragile and bad practice. Conversely, there are many places where we have not escaped underscores but needed to. Escape all underscores that do not appear in preformatted blocks or preformatted spans and are not themselves delineating emphasized spans. The changes in this commit are exactly the result of executing the following Bash code: ```bash e=':x;' # begin loop e+='s/^' # anchor match at beginning of line e+='(' # begin capturing subexpression e+='(' # begin list of alternatives e+='[^`_\\]|' # any mundane character, or e+='`([^`\\]|\\.)*`|' # backtick-enclosed span, or e+='\b_|_\b|' # underscore at boundary, or e+='\\.' # backslash-escaped character e+=')*' # any number of the preceding alternatives e+=')' # end capturing subexpression e+='\B_\B/\1\\_/;' # escape non-formatting underscore e+='tx' # repeat loop if we escaped an underscore escape_underscores=( sed # use extended regular expressions -E # skip over indented blocks (following an empty line) -e '/^$/{:i;n;/^( {4,}|\t)/bi}' # skip over preformatted blocks -e '/^\s*```/,/^\s*```/{p;d}' # skip over generated sections -e '/GENERATE-FROM-SCHEMA-START/,/GENERATE-FROM-SCHEMA-END/{p;d}' # escape underscores -e "${e}" ) "${escape_underscores[@]}" -i doc/*.[0-9].md ``` Changelog-None

The **makesecret** RPC command derives a secret key from the HSM\_secret.
One of *hex* or *string* must be specified: *hex* can be any hex data,
*string* is a UTF-8 string interpreted literally.
RETURN VALUE
------------
[comment]: # (GENERATE-FROM-SCHEMA-START)
On success, an object is returned, containing:
- **secret** (secret): the pseudorandom key derived from HSM\_secret (always 64 characters)
[comment]: # (GENERATE-FROM-SCHEMA-END)
The following error codes may occur:
- -1: Catchall nonspecific error.
