将RSA密钥导入iPhone钥匙串？ [英] Import RSA keys to iPhone keychain?

问题描述

我有几个NSString对象表示RSA公共 - 私人密钥对（不是由SecKeyCreatePair生成，而是由外部加密库）。如何从这些NSString对象创建SecKeyRef对象（这是SecKeyDecrypt / Encrypt方法所需的）？

I have a couple of NSString objects that represent an RSA public-private keypair (not generated by SecKeyCreatePair, but by an external crypto library). How can I create SecKeyRef objects (which are required for the SecKeyDecrypt/Encrypt methods) from these NSString objects?

我需要先将它们导入Keychain吗？如果是，如何？

Do I need to import them into the Keychain first? If so, how?

谢谢！

推荐答案

用正确的标志集调用 SecItemAdd 。请参阅： http：//hg.mozilla .org / services / fx-home / file / tip / Sources / NetworkAndStorage / CryptoUtils.m＃l931

The answer was to call SecItemAdd with the right set of flags. See: http://hg.mozilla.org/services/fx-home/file/tip/Sources/NetworkAndStorage/CryptoUtils.m#l931
