comment Are modified implementations of cryptographic algorithms a good idea?
I'm not getting what you mean by "modified implementations" and "algorithms are not standard"

comment how to use common modulus attack?
Oh right, so this means the message from both parties is multiplied by s1 and s2 respectively right?

@mikeazo how did you move to the 2nd step where M^e^s1 became M^e*s1

comment Shor's Algorithm values
@daniel however, if r wasn't even then we should return to the first step of the classical part right? as in choose a different a where a<N (N= the number we want to factor)

@daniel i think i am, but how is r/2 =-1 leading to r=-2?

comment Decrypting Triple-DES using 2 keys in crypto tools
This makes sense, so your saying to decrypt i will use c4 and lets say the last message as an IV to begin with?

comment Decrypting Triple-DES using 2 keys in crypto tools
Great, but for the first decryption process what is the IV going to be? I mean I will start off by the cipher text I got, then I'll decrypt it with K2 then Encrypt it with K1 then Decrypt it with K2 again then that result I'll XOR it with the IV..am I right?
