It's a short extra step for small programs, but can save a lot of time in large projects since it allows the developer to only recompile the code that was changed.

Hi guys,
I want to encrypt/decrypt a file
with AES in CTR mode using crypto++ library.
To encrypt a file using AES in CTR mode
the solution is something like this
  1. int CRYPTOPP_API main(int argc, char *argv[])
  2. {
  3. std::string command, executableName, macFilename;
  4. if (argc < 2)
  5. command = 'h';
  6. else
  7. command = argv[1];
  8. if (command 'ae')
  9. AES_CTR_Encrypt(argv[2], argv[3], argv[4], argv[5]);
  10. }
  11. void AES_CTR_Encrypt(const char *hexKey, const char *hexIV, const char *infile, const char *outfile)
  12. {
  13. SecByteBlock key = HexDecodeString(hexKey);
  14. SecByteBlock iv = HexDecodeString(hexIV);
  15. CTR_Mode<AES>::Encryption aes(key, key.size(), iv);
  16. FileSource(infile, true, new StreamTransformationFilter(aes, new FileSink(outfile)));
  17. }
This is the solution as per given in crypto++ lib
In the command line if I pass
  1. crypttest '2b7e151628aed2a6abf7158809cf4f3c' '000102030405060708090a0b0c0d0e0f' samp.txt encoded.txt
where
  1. '2b7e151628aed2a6abf7158809cf4f3c' is my key;
  2. '000102030405060708090a0b0c0d0e0f' is my initialization vector;
The file is encoded fine.
Now suppose I have a password
const char* password = 'somePassword';
Now I want the file to be encoded using this password. How do I do this?
I tried passing 'password' as arg[2] in AES_CTR_Encrypt function, I get error telling
  1. 'CryptoPP::Exception caught: AES/CTR: 1 is not a valid key length'
Also I have problem using argv[3] in AES_CTR_Encrypt function which is initialization
vector. How do I calculate different IV values for different files???
Problem decrypting the same file
To decrypt the file with the same password, I tried defining
  1. void AES_CTR_Decrypt(const char *hexKey, const char *hexIV, const char *infile, const char *outfile)
  2. {
  3. SecByteBlock key = HexDecodeString(hexKey);
  4. SecByteBlock iv = HexDecodeString(hexIV);
  5. CTR_Mode<AES>::Decryption aes(key, key.size(), iv);
  6. FileSource(infile, true, new StreamTransformationFilter(aes, new FileSink(outfile)));
  7. }
but I dont get back the original file.
What is that I need to decrypt a file????
How can I encrypt/decrypt a file with AES in CTR mode when I have a password????
