Interface BCryptFormatter

All Known Implementing Classes:

BCryptFormatter.Default

public interface BCryptFormatter

Formats the out hash message of bcrypt. Usually this is the Modular Crypt Format. Example

     $2a$12$US00g/uMhoSBm.HiuieBjeMtoN69SN.GE25fCpldebzkryUyopws6
 

Which consists of the version identifier:

     $2a$
 

the cost factor:

     12$
 

16 bytes Radix64 encoded UTF-8 bytes of salt:

     uMhoSBm.HiuieBjeMtoN69
 

and 23 Radix64 encoded UTF-8 bytes of actual bcrypt hash

     MtoN69SN.GE25fCpldebzkryUyopws6
 

The literal $ is a simple seperator
