Hi,

1st link was to simply show mention of longer bit length SHA
algorithms in Android SDK, not how to go about effectively using them,
which usually involves 'salt' and other measures as other have
discussed here and else where.

MD5 (128 bits) is 'weaker' than SHA1 (160 bits) only by virtue of
having less bits, without seeking to start an argument both are
'broken/have collisions' in theory/practice anyway, hence SHA3 contest
