Thanks a lot for your suggestion. I too noticed that the first 8 bytes only
have problem. I will try on other platform and verify this.

Have you tried the same code on some other platform like Linux or Windows?
I don't have time to look over your code, but I did notice that the first 8
bytes of the output are not what you expected and the remaining data is
decrypted correctly. Seems like maybe you need to initialise a salt/IV
value. I'm running OpenSSL on a StrongARM (Windows CE) and haven't seen
any
problems like this.

Hi,
I am trying to port openssl on vxWorks(Tornado 2.0 vxWorks 5.4) for
StrongArm(ixp1200) platform. I have a problem here. The encryption is not
working for me. My code is as given below. I am using 3DES encryption
first.
Then to verify the output I am doing a decryption for the encrypted output.
I am not getting the original input after decryption. I am not enabling
DES_PTR or DES_UNROLL or any other flags in particular. Does anyone know
what is going wrong here?
T_VOID DoCipher(T_VOID* pCipherCtx)
{
int i;
T_UCHAR8 *OutputBuf = calloc(64,sizeof(T_UCHAR8));
T_UCHAR8 *OutputBuf2 = calloc(64,sizeof(T_UCHAR8));
T_UCHAR8 InputBuf[] = {
0x30 ,0x31 ,0x32 ,0x33 ,0x34 ,0x35 ,0x36 ,0x37,
0x38 ,0x39 ,0x0a ,0x61 ,0x62 ,0x63 ,0x64 ,0x65,

};
((EVP_CIPHER_CTX*)pCipherCtx)-encrypt = 1; /* Encrypt data first */
printf(\n\r Calling Encryption, EncryptFlag =%d \n\r InputData =
\n\r,((EVP_CIPHER_CTX*)pCipherCtx)-encrypt);
for(i=0;i64;i++)
printf(%x ,*(InputBuf+i));
/* This 'do_cipher' invokes 'des_cbc_ede_cipher' from 'e_cbc_3d.c' file */
((EVP_CIPHER_CTX*)pCipherCtx)-cipher-do_cipher((EVP_CIPHER_CTX*)pCipherCtx
,OutputBuf,
InputBuf,64);/* Encryption function */
printf(\n\r Finished Encryption, EncryptFlag =%d \n\r OutputData =
\n\r,((EVP_CIPHER_CTX*)pCipherCtx)-encrypt);
for(i=0;i64;i++)
printf(%x ,*(OutputBuf+i));
((EVP_CIPHER_CTX*)pCipherCtx)-encrypt = 0; /* Decrypt the output data */
printf(\n\r Calling Decryption, EncryptFlag =%d \n\r InputData =
\n\r,((EVP_CIPHER_CTX*)pCipherCtx)-encrypt);
for(i=0;i64;i++)
printf(%x ,*(OutputBuf+i));

((EVP_CIPHER_CTX*)pCipherCtx)-cipher-do_cipher((EVP_CIPHER_CTX*)pCipherCtx
,OutputBuf2,
OutputBuf,64); /* Decryption function */
printf(\n\r Finished Decryption, EncryptFlag =%d \n\r OutputData =
\n\r,((EVP_CIPHER_CTX*)pCipherCtx)-encrypt);
for(i=0;i64;i++)
printf(%x ,*(OutputBuf2+i));
return;
}
My printf results are as follows

Does anyone has specific files- Configure/Makefile -for vxworks strongarm
platform? Or anyone knows which all flags need to be enabled for vxWorks
strongarm platform? Or where can I find the detailed procedure for vxWorks
platform compilation/installation?
Please help. I am new to openssl porting area.
Thanks in advance,
Best Regards,
BPaul

Subject: OCSP app bug
Date: Wed, 20 Nov 2002 14:46:19 -0500
The OCSP app seems to not handle the -rother option correctly.
Look at apps/ocsp.c. The 'rcertfile' variable in main() is
set when you give the app the -rother option, but then
it's not used in the load_certs() invocation.
This effectively hangs the ocsp app when the -rother switch
is used, since it's trying to read certs from stdin.
