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
Calling Encryption, EncryptFlag =1
InputData =
30 31 32 33 34 35 36 37 38 39 a 61 62 63 64 65 66 67 68 69 6a a 6b 6c 6d 6e 6f 70 71 72 73 74 a 75 76 77 78 79 7a 2e 2e 2e 2e a 41 42 43 44 45 46 47 48 49 4a 4b 4c 4d 4e 4f 50 51 52 53

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

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. cj
