Hi.

I installed libxyssl-dev and it populated a directory with a number of examples. The one I found useful for this thread is a c code, uploaded (below) as a txt file. It is from:
Code:
/usr/share/doc/libxyssl-dev/examples/hash/sha1sum.c

on a GNU/Debian system:
Code:
OS, ker|rel, machine: Linux, 2.6.26-2-amd64, x86_64
Distribution        : Debian GNU/Linux 5.0

I wote a quick perl code and compared a few other methods to calculate the sha1 hash. The results are:
Code:
Whole: 15:0:15 of 4 lines in file "data1"
Now is the time
for all good men
to come to the aid
of their country.
 || end

-----
 Results, perl:
7de790fbe559d66cf890671ea2ef706281a1017f  data1 (perl)

-----
 Results, sha1sum:
7de790fbe559d66cf890671ea2ef706281a1017f  data1

-----
 Results, openssl OpenSSL 0.9.8g 19 Oct 2007:
SHA1(data1)= 7de790fbe559d66cf890671ea2ef706281a1017f

-----
 Results, sample c code ( 156 lines ):
-rwxr-xr-x 1 26335 Jul  3 13:14 a.out
7de790fbe559d66cf890671ea2ef706281a1017f  data1 (c code)

Your install will probably have placed relevant files in places different from those for my install.

Best wishes ... cheers, drl

NAME
Locale::Codes::LangExt - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangExt; $lext = code2langext('acm'); # $lext gets 'Mesopotamian Arabic' $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm' @codes = all_langext_codes(); @names = all_langext_names(); DESCRIPTION
The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in the IANA language registry. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language registry codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language extensions. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langext('acm','alpha'); $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic. This is the default code set. ROUTINES
code2langext ( CODE [,CODESET] ) langext2code ( NAME [,CODESET] ) langext_code2code ( CODE ,CODESET ,CODESET2 ) all_langext_codes ( [CODESET] ) all_langext_names ( [CODESET] ) Locale::Codes::LangExt::rename_langext ( CODE ,NEW_NAME [,CODESET] ) Locale::Codes::LangExt::add_langext ( CODE ,NAME [,CODESET] ) Locale::Codes::LangExt::delete_langext ( CODE [,CODESET] ) Locale::Codes::LangExt::add_langext_alias ( NAME ,NEW_NAME ) Locale::Codes::LangExt::delete_langext_alias ( NAME ) Locale::Codes::LangExt::rename_langext_code ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangExt::add_langext_code_alias ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangExt::delete_langext_code_alias ( CODE [,CODESET] ) These routines are all documented in the Locale::Codes::API man page.
