Besides incorporating a salt to protect against rainbow table attacks, bcrypt is an adaptive function: over time, the iteration count (rounds) can be increased to make it slower, so it remains resistant to brute-force search attacks even with increasing computation power.<br><br>Enter the password in the input to generate its hash.";
