Hello again,
I'm going to use following algorithm:
key_size=0
string=pass-phrase
key_from_string=""
while(key_size < key_required_size)
{
key_from_string+=SHA1(string)
string+=key_from_string
key_size += 20 bytes
}
The obtained key_from_string is key for encryption.
Is it secure to use following algorithm?
Does CryptoPP suggests something better?
Best Regards,
Voronkov Konstantin
