iphone - How to print the public key of a certificate (Objective-C) -

-

I have a certificate. P12 and .crt and I have to store the public key to print it and the key iPhone application I have seen the documentation of the iPhone, but I can not do this ...

This is surprisingly easy. You do not need to add a certificate for the keychain to handle this case. Rather, just load the certificate data (i.e., the contents of a .cer file) in your application (you can either get from your bundle or turn off the network) and then underline a certificate using SecCertificateCreateWithData Please. From there you can remove a public key ref by using a SecTrust object (SecTrustCreateWithCertificates, SecTrustEvaluate - you can choose to ignore the resulting SecTrustResultType- and SecTrustCopyPublicKey). And from there you can encrypt and verify using SecKey APIs (SecKeyEncrypt, SecKeyRawVerify).

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
