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.

Subject: Building openssl-0.9.7-beta4
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,
0x66 ,0x67 ,0x68 ,0x69 ,0x6a ,0x0a ,0x6b ,0x6c,
0x6d ,0x6e ,0x6f ,0x70 ,0x71 ,0x72 ,0x73 ,0x74,
0x0a ,0x75 ,0x76 ,0x77 ,0x78 ,0x79 ,0x7a ,0x2e,
0x2e ,0x2e ,0x2e ,0x0a ,0x41 ,0x42 ,0x43 ,0x44,
0x45 ,0x46 ,0x47 ,0x48 ,0x49 ,0x4a ,0x0a ,0x4b,
0x4c ,0x4d ,0x4e ,0x4f ,0x50 ,0x51 ,0x52 ,0x53
};
((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;i<64;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;i<64;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;i<64;i++)
printf("%x ",*(OutputBuf+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
,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;i<64;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
