The template consists of any number of “character replacement” and “character literal” sequences. A “character replacement” sequence starts with a left brace, has any number of special replacement characters, and ends with a right brace. A character literal can be any character except a brace or a backslash. A literal brace or backslash character can be included in the output by escaping with a backslash.

The following replacement characters can be used in a replacement sequence:

• ”#”: a random digit
• “a”: a random lower case letter
• “A”: a random upper case letter
