From bff052ec2da81e414902f18d26192a16c8447863 Mon Sep 17 00:00:00 2001 From: ryker Date: Mon, 5 Oct 1998 20:13:15 +0000 Subject: Import of SSLeay-0.9.0b with RSA and IDEA stubbed + OpenBSD build functionality for shared libs. Note that routines such as sslv2_init and friends that use RSA will not work due to lack of RSA in this library. Needs documentation and help from ports for easy upgrade to full functionality where legally possible. --- lib/libcrypto/rc4/rc4s.cpp | 73 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 73 insertions(+) create mode 100644 lib/libcrypto/rc4/rc4s.cpp (limited to 'lib/libcrypto/rc4/rc4s.cpp') diff --git a/lib/libcrypto/rc4/rc4s.cpp b/lib/libcrypto/rc4/rc4s.cpp new file mode 100644 index 00000000000..39f1727dd3f --- /dev/null +++ b/lib/libcrypto/rc4/rc4s.cpp @@ -0,0 +1,73 @@ +// +// gettsc.inl +// +// gives access to the Pentium's (secret) cycle counter +// +// This software was written by Leonard Janke (janke@unixg.ubc.ca) +// in 1996-7 and is entered, by him, into the public domain. + +#if defined(__WATCOMC__) +void GetTSC(unsigned long&); +#pragma aux GetTSC = 0x0f 0x31 "mov [edi], eax" parm [edi] modify [edx eax]; +#elif defined(__GNUC__) +inline +void GetTSC(unsigned long& tsc) +{ + asm volatile(".byte 15, 49\n\t" + : "=eax" (tsc) + : + : "%edx", "%eax"); +} +#elif defined(_MSC_VER) +inline +void GetTSC(unsigned long& tsc) +{ + unsigned long a; + __asm _emit 0fh + __asm _emit 31h + __asm mov a, eax; + tsc=a; +} +#endif + +#include +#include +#include "rc4.h" + +void main(int argc,char *argv[]) + { + unsigned char buffer[1024]; + RC4_KEY ctx; + unsigned long s1,s2,e1,e2; + unsigned char k[16]; + unsigned long data[2]; + unsigned char iv[8]; + int i,num=64,numm; + int j=0; + + if (argc >= 2) + num=atoi(argv[1]); + + if (num == 0) num=256; + if (num > 1024-16) num=1024-16; + numm=num+8; + + for (j=0; j<6; j++) + { + for (i=0; i<10; i++) /**/ + { + RC4(&ctx,numm,buffer,buffer); + GetTSC(s1); + RC4(&ctx,numm,buffer,buffer); + GetTSC(e1); + GetTSC(s2); + RC4(&ctx,num,buffer,buffer); + GetTSC(e2); + RC4(&ctx,num,buffer,buffer); + } + + printf("RC4 (%d bytes) %d %d (%d) - 8 bytes\n",num, + e1-s1,e2-s2,(e1-s1)-(e2-s2)); + } + } + -- cgit v1.2.3
