RFC 2616 section 14.15:

[...]
   The Content-MD5 entity-header field, as defined in RFC 1864 [23], is
   an MD5 digest of the entity-body for the purpose of providing an
   end-to-end message integrity check (MIC) of the entity-body. (Note: a
   MIC is good for detecting accidental modification of the entity-body
   in transit, but is not proof against malicious attacks.)
[...]

Tony.
