SCOS was never meant to be in any way 'secure'. Hense the name: (S)ci (C)rypt (O)pen (S)ecret. It was meant as a fun exercise at cryptanalysis and working out a crypt/decrypt algorithm given examples of encrypted messages. > Maybe worth a little challenge, to have such a format for sci.crypt, > with an AZ encoder, a pad and seriation program. :-) And why would you think it would not also eventually be "cracked" and "floating around on bitmessage" after some time?
