you are using a fast hashing algorithm. You want password hashing to be slow to mitigate brute-force attacks. you are not salting your hash. Salting means adding some random data to the password prior to hashing, then storing the random data along with the hash This is a C++ class that implements the Secure Hash Algorithm SHA-1. It is similarly difficult, using only the hash, to determine the original bit string. SHA-1 produces a 20 byte (160 bit) hash. The SHA-1 hash is currently used for security, however the intended purpose of this library is for file verification.. SHA-1 or Secure Hash Algorithm 1 is a cryptographic hash function which takes an input and produces a 160-bit (20-byte) hash value.
