Improvements required in Passphrase generator

[reyraa]

Expected behaviour

• parseInt uses a radix value to parse the given value for decimal, hex or any other radix.
• Improvements in documentations is required.
• L35 is redundant.

Actual behaviour

• The usage of parseInt is not correct in some cases.
• We're generating string literal to parse the value in hex
• Descriptions are not clear enough
• noop code in L35 must be removed.
