RC4 Compatibility with WinBlows.
Hi, I'm using the OpenSSL cryptlib encryption tools shipped with the Mac OS-X. I'm unable to decrypt a text file encrypted on a Windows XP, using the CryptEncrypt functon, an API in windows. The file was encrypted with a 16 byte key (128 bits) on the Windows. Using RC4 stream cypher. Yea, I know RC4 is weak, but my application requires I be able to use it for compatibility reasons. I'm decrypting it via the EVP_DecryptInit, EVP_DecryptUpdate EVP_DecryptFinal set of library calls. I can furnish the exact source code to anyone interested in helping me, via private Email. If others express an interest, I'll post the solution to the net if anyone wants it. Has anyone on this list run into problems where data encrypted using the WinBlows API's are not able to be decrypted using the Mac OS-X (FreeBSD) openSSL libraries or cryptlib. I'm using the exact same symmetric key. I can furnish the test files to anyone who can help me.

Has anyone else had these problems? Is there a work-around?
I'm trying to build OpenSSL on OpenBSD3.4 The version I'm using is openssl-0.9.7b I was un-sucessful in getting it to build via using ./config So I tried... ./config no-asm After noticing in the FAQ that the 'no-asm' option was needed. So here is the last portion of the output of ./config... cut here --- Makefile = Makefile.ssl making links in tools... Makefile = Makefile.ssl generating dummy tests (if needed)... Configured for OpenBSD-i386. The library could not be configured for supporting multi-threaded applications as the compiler options required on this system are not known. See file INSTALL for details if you need multi-threading. - What do they mean in that last paragraph above? Is this because the new OpenBSD3.4 compiler is changed? So - now when I do the 'make' I get... # make making all in crypto... gcc -I. -I.. -I../include -DDSO_DLFCN -DHAVE_DLFCN_H -DOPENSSL_NO_KRB5 -DOPENSSL_NO_ASM -DL_ENDIAN -DTERMIOS -O3 -fomit-frame-pointer -c cryptlib.c *unknown*: Assembler messages: *unknown*:0: Warning: as: I don't understand 'Q' flag. *unknown*:0: Warning: as: I don't understand 'y' flag. /tmp/cced7503.s:4: Error: Alignment too large: 15. assumed. /tmp/cced7503.s:41: Error: Unknown pseudo-op: `.section' *** Error code 1 Whats up with this? What am I doing wrong? I thought I was following the instructions... __ OpenSSL Project http://www.openssl.org User Support Mailing List[EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
Problems building openssl-0.9.7b
Hi, I cannot build openssl-0.9.7b under OpenBSD3.4. Has anyone else been sucessful in getting this to build? My first errors occur here ../libcrypto.a(md5_dgst.o): In function `MD5_Update': md5_dgst.o(.text+0xec): undefined reference to `md5_block_asm_host_order' This is the first occurance of this problem. Could someone please help me out? By the way, I did look through the archives and didn't see anyone else posting this problem.
