Simple REXX mailto script

Yet another mailto command line tool, rxmailto.cmd v0.1 can so far send one text mail to one receiver via a Mail Submit Agent (MSA) at port 587 supporting SMTP AUTH with CRAM-MD5 and 8bitMIME. That's the minimum I could get away with after the spam flood finally drowned my old mailbox.

Various details are far from perfect, e.g. if a run of words with non-ASCII characters in the subject is longer than 56 octets the subject encoder will emit a folded line longer than 76 characters, and that's not permitted by RFC 2047. On the other hand the script won't break UTF-8 characters in the subject for platforms with UTF-8 as local charset. You get what you pay for, less than 30 KB. ;-)

MD5 test suite 1.2

The MD5 test suite version 1.2 finally supports streaming and bit string input:

   hash = MD5( bytes )          ==> MD5 of an octet string
   ctxt = MD5( bytes, '' )      ==> init.  new MD5 context
   ctxt = MD5( bytes, ctxt )    ==> update old MD5 context
   hash = MD5( /**/ , ctxt )    ==> finalize   MD5 context
   hash = MD5( bytes, /**/, n ) ==> MD5 of n zero-fill bits
   ctxt = MD5( bytes, ''  , n ) ==> init.  MD5 bit context
   ctxt = MD5( bytes, ctxt, n ) ==> update MD5 bit context

Also added: APR1 can determine the hashed passwords used by BSD and Apache htpasswd. This is a function also offered by openssl passwd -1 and openssl passwd -apr1, for details see a manual of the openssl command line tool.
