问题 Does anyone know of a good implementation of bcrypt, I know this question has been asked before but it got very little response.

I have found some nice ways of getting a Blowfish hash, but I am still unsure about the conversion approach that I should use. Here are my options: Option 1 Every time a user logs in, I check if the hash starts with $2. If not, I assume it is sha1, take the password entered by the user, get the bcrypt
