Actually our RC2 implementation supports any key size >= 40 bit.  I
can't remember why I came up with the two identifiers

    GCRY_CIPHER_RFC2268_40  = 307,  /* Ron's Cipher 2 (40 bit). */
    GCRY_CIPHER_RFC2268_128 = 308,  /* Ron's Cipher 2 (128 bit). */

and didn't implement the second one.  Actually GCRY_CIPHER_RFC2268 would
have been sufficient because the caller may use any keylength anyway.

I added a Changelog entry and pushed it to master.



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
