>Description:

Recent changes (to openssl or netpgp) did break the atf tests for netpgpverify
on sparc64.

>How-To-Repeat:

Extract the dsa-pubring.gpg and in2.asc files from 
/usr/tests/usr.bin/netpgpverify/t_netpgpverify by uudecoding the respective
chunks. Then:

gdb netpgpverify
(gdb) break digest_init
(gdb) run -k dsa-pubring.gpg in2.asc
(gdb) cont
(gdb) cont
(gdb) cont
(gdb) p hashalg
$1 = 0

and watch:

109             switch(hash->alg = hashalg) {
110             case MD5_HASH_ALG:
...
145             default:
146                     printf("hash_any: bad algorithm\n");
147                     return 0;
148             }

... hit the default case and fail.
