I'm given a specific number (sayn)to use "as an encryption key," and I have to find the decryption key.

Isnthe same as the encryption exponent?

So is the encryption key the same as the public key exponent

? The number I'm supposed to use as an encryption key is even, and it seems like it can't be the public key exponent because phi(m)=(p-1)(q-1) is also even.*e* - November 10th 2013, 02:48 PMSlipEternalRe: RSA/cryptography question
It sounds like you are given , not . So, you need to find . Then the decryption key would be ? I dunno.

Oh, just read through the link I sent you. It tells you precisely what to do in the section titled "A working example".

Is there any way to use an even number as an encryption exponent?
