| Basic build instructions |
| ------------------------ |
| |
| 1. Build it:: |
| |
| make |
| |
| 2. Run it:: |
| |
| erl -pa ebin |
| |
| Basic usage instructions |
| ------------------------ |
| |
| 1. Start the `sasl` and `crypto` applications:: |
| |
| 1> ok = application:start(sasl). |
| ok |
| 2> ok = application:start(crypto). |
| ok |
| |
| 2. Hash a password using a salt with the default number of rounds:: |
| |
| 4> Hash = bcrypt:hashpw("foo", bcrypt:gen_salt()). |
| "$2...000" |
| |
| 3. Verify the password:: |
| |
| 5> Hash =:= bcrypt:hashpw("foo", Hash). |
| true |
| 6> Hash =:= bcrypt:hashpw("bar", Hash). |
| false |
