Whatever one you type on the command-line. It all comes down to the
JVM's support plus any extensions you've added (BouncyCastle, etc.) to
support other message digest algorithms.

$ bin/digest.sh  -a MD2 foo
foo:d11f8ce29210b4b50c5e67533b699d02

$ /usr/local/apache-tomcat-7.0.32/bin/digest.sh  -a MD5 foo
foo:acbd18db4cc2f85cedef654fccc4a4d8

$ bin/digest.sh  -a SHA-1 foo
foo:0beec7b5ea3f0fdbc95d0dd47f3c5bc275da8a33

$ bin/digest.sh  -a SHA-2 foo
foo:Nov 6, 2012 9:58:30 AM org.apache.catalina.realm.RealmBase Digest
SEVERE: java.security.NoSuchAlgorithmException: SHA-2 MessageDigest
not available
foo

$ bin/digest.sh  -a SHA-256 foo
foo:2c26b46b68ffc68ff99b453c1d30413413422d706483bfa0f98a5e886266e7ae

My JVM also supports SHA-384 and SHA-512.
