SecKeyRef from exponent modulus I would like to decrypt a RSA encoded blob on iPhone by having an exponent and modulus as private key. In Java with javax.crypto this could be easily achieved by code like this 1 key RSAPublicKeySpec keySpec.. generating a pair or importing a certificate which I don't have want. Is there a way to create a key manually having a modulus exponent If so can you give me a clue on how Thanks in advance iphone ios security rsa share improve this question ..

laying out images in UIScrollView automatically

http://stackoverflow.com/questions/6488169/laying-out-images-in-uiscrollview-automatically

the row I need to add xOffsetBetweenOrigins once and if I am on the third I need to add it twice. To do this I use the modulus operator. It gives me the remainder of a division operation so when I say imageNumber numPerRow I am asking for the remainder.. the remainder is 1 so I get xOffsetBetweenOrigins 1. For the y value I do something similar but instead of taking the modulus I simply divide imageNumber numPerRow and round down. Doing this I will get 0 for 0 1 and 2. I will get 1 for 3 4 and 5...
