| Note |
| that this method is only likely to be used in more complex environments that wish to format and/or save the |

| <A HREF="../../../../../org/apache/shiro/authc/credential/PasswordService.html#encryptPassword(java.lang.Object)"><CODE>encryptPassword</CODE></A> method suitable enough for safety |
| and ease-of-use. |
| <h3>Usage</h3> |
| The input argument type can be any 'byte backed' <code>Object</code> - almost always either a |
| String or character array representing passwords (character arrays are often a safer way to represent passwords |
| as they can be cleared/nulled-out after use. Any argument type supported by |
| <CODE>ByteSource.Util#isCompatible(Object)</CODE> is valid. |
| <p/> |
| Regardless of your choice of using Strings or character arrays to represent submitted passwords, you can wrap |
| either as a <code>ByteSource</code> by using <CODE>ByteSource.Util</CODE>, for example, when the passwords are captured as |
| Strings: |
| <pre> |
| ByteSource passwordBytes = ByteSource.Util.bytes(submittedPasswordString); |
| Hash hashedPassword = hashingPasswordService.hashPassword(passwordBytes); |
| </pre> |
| or, identically, when captured as a character array: |
| <pre> |
| ByteSource passwordBytes = ByteSource.Util.bytes(submittedPasswordCharacterArray); |
| Hash hashedPassword = hashingPasswordService.hashPassword(passwordBytes); |
