Subject [jira] Commented: (CASSANDRA-2107) MessageDigests are created in several places, centralize the creation and error handling
Date Sat, 05 Feb 2011 02:53:30 GMT

Matthew F. Dennis commented on CASSANDRA-2107:
----------------------------------------------

The above link is from SVN revision 2 on Sep 15, 2009 "initial code dump".  It doesn't look
like MessageDigestAlgorithm (or any equivalent) exists in Guava (even in r2 despite the fact
that it has javadoc for it).

> MessageDigest.getInstance("SomeAlg") throws NoSuchAlgorithm exception (a checked exception).
 This is annoying as it causes everyone that uses standard algs like MD5 to surround their
code in try/catch.  We should concentrate the creation in one method that doesn't raise an
exception (i.e. catches NoSuchAlgorithm and raises a RuntimeException) just to clean the code
up a little.
