Hi All,
Has anybody been able to get Padlock accelerated SHA1 working on a C7
or is this not currently possible?
The CPU has the capability:
OpenBSD 4.4 (GENERIC) #1021: Tue Aug 12 17:16:55 MDT 2008
dera...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC
cpu0: VIA C7 Processor 1800MHz ("CentaurHauls" 686-class) 1.80 GHz
cpu0:
FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,CMOV,PAT,CFLUSH,ACPI,MMX,FXSR,SSE,SSE2,TM,SBF,SSE3,EST,TM2,xTPR
cpu0: RNG AES AES-CTR SHA1 SHA256 RSA
..but on http://www.openbsd.org/crypto.html only the C3 processor is
listed, which doesnt have SHA1.
Speed with and without -evp is the same:
#openssl speed -evp sha1
type 16 bytes 64 bytes 256 bytes 1024 bytes
8192 bytes
sha1 5182.12k 16114.78k 37209.11k 55274.13k
65219.75k
#openssl speed sha1
type 16 bytes 64 bytes 256 bytes 1024 bytes
8192 bytes
sha1 5200.49k 16100.77k 36993.16k 55122.71k
64871.91k
Many thanks!
