the status of HP-UX IA64,


As I understand it, HP-UX on IA64 has normal "factory" support through 
to the end of 2025 "at least"; I expect there'll be options to pay a lot 
for support beyond the end of factory support.

on top.


Personally, I'm bemoaning the lack of a rc4-romp.pl for AIX 2 on my RT PC. And 
the shocking lack of assembly modules for the PDP-11.

In all seriousness: It's pretty cool that OpenSSL still includes assembly 
modules for what are now rather niche architectures such as MIPS and PA-RISC. 
And in case all this is too convoluted for the OP, rc4-ia64.pl doesn't apply to 
extant AIX systems, which are all some variant of POWER, not IA64.

MIPS is still a common platform in Linux-based routers, which generally
use OpenSSL as their main cryptographic library for everything from WiFi
security to OpenVPN and browser configuration.  As these are often speed
constrained chips, assembler optimizations are important.  While ARM was
making inroads in this market, RiscV or an Asian design are more likely
successor for low cost low power router hardware.

(OK, somewhere someone probably has one of the other AIX variants running - 
AIX/390 might be the last non-POWER AIX to die, if I had to bet. But probably 
not AIX IA64.)



Enjoy

Hi,

Thanks for all the information related to missing rc4 assembly file for
IA-64 architecture.

*Richard : * The following mentioned degradation on nt64 compared to the
same openssl version 1.1.1 build with out using the flags "
"enable-weak-ssl-ciphers" and "
 enable-deprecated" .

Thanks and Regards,
Ram Krushna

It got remove as part of a larger cleanup commit:

commit 624265c60e07f8e5f251d0f5b79e34cf0221af73
Author: Rich Salz 
Date:   Thu Jun 15 12:03:40 2017 -0400

Cleanup some copyright stuff

Remove some incorrect copyright references.
Move copyright to standard place
Add OpenSSL copyright where missing.
Remove copyrighted file that we don't use any more
Remove Itanium assembler for RC4 and MD5 (assembler versions of old and
weak algorithms for an old chip)
Standardize apps/rehash copyright comment; approved by Timo
Put dual-copyright notice on mkcert

Degradation, compared to what?

Reg missing rc4-ia64.pl in openssl 1.1.1

[ramakrushna mishra]

Hi,

In Openssl 1.1.1,  the file "rc4-ia64.pl" is missing. This cause
degradation of performance on AIX.  Is this intentional for deprecating the
support for RC4 ?

Similarly If I build Openssl 1.1.1 on nt64  with flags
"*enable-weak-ssl-ciphers"
and "**enable-deprecated"  , *I witness degrade in performance.  Could you
please help me understand how these flags can be related to speed test of
all ciphers and digests ?

Thanks and Regards,
Ram Krushna
