I have tried both solutions does not work. I have tried all I could with no
avail. Can you try to decrypt this string below and see if it works? I want
to confirm its not something funny with the encryption nor password!
String:
C53ED32B2F20C2C19786F507671D9BA6AE80298C1C6C04583037498F4A910A3255FD02E53664118AEA315A577A80FCEF
Password: password
I have just encrypted with:
CryptoPP::StringSource ss(
charToEncrypt, true,
new CryptoPP::DefaultEncryptorWithMAC(
(byte*)pass.data(), pass.size(),
new CryptoPP::HexEncoder(
new CryptoPP::StringSink(outstr)
)
)
);
