[英]Generate SecKeyRef from base64 RSA public key
I have looked at other answers on StackOverflow and I didn't find what I was looking for. 我在StackOverflow上查看了其他答案,但我找不到我要找的东西。 I have a public RSA key in Base64 format generated by some other system. 我有一个其他系统生成的Base64格式的公共RSA密钥。 It is in x509 format and the encryption is 512 bits strong. 它采用x509格式,加密强度为512位。
I need to create a SecKeyRef in order to use an encrypt some data and send back home. 我需要创建一个SecKeyRef,以便使用加密一些数据并发送回家。 (for all purposes the public key is sent from the server side) (出于所有目的,公钥从服务器端发送)
I can't find anything on the web that helps me in this situation, all other examples and answers by-pass the problem. 我在网络上找不到任何可以帮助我解决这个问题的方法,所有其他的例子和答案都可以解决问题。 I can't create a PEM or DER files or use any other 'tricks', Base64 -> SecKeyRef nothing less. 我无法创建PEM或DER文件或使用任何其他'技巧', Base64 - > SecKeyRef 。
I know this is a hard one so thank you all for helping. 我知道这很难,所以谢谢大家的帮助。
ps this is for a framework and not an app. ps这是一个框架,而不是一个应用程序。
