1.1 23/08/96 - eay
Changed RC2_set_key() so it now takes another argument. Many
thanks to Peter Gutmann <pgut01@cs.auckland.ac.nz> for the
clarification and original specification of RC2. BSAFE uses
this last parameter, 'bits'. It the key is 128 bits, BSAFE
also sets this parameter to 128. The old behaviour can be
duplicated by setting this parameter to 1024.
1.0 08/04/96 - eay
First version of SSLeay with rc2. This has been written from the spec
posted sci.crypt. It is in this directory under rrc2.doc
I have no test values for any mode other than ecb, my wrappers for the
other modes should be ok since they are basically the same as
the ones taken from idea and des :-). I have implemented them as
little-endian operators.
While rc2 is included because it is used with SSL, I don't know how
far I trust it. It is about the same speed as IDEA and DES.
So if you are paranoid, used Tripple DES, else IDEA. If RC2
does get used more, perhaps more people will look for weaknesses in
it.
