Does Commom Crypto library supports below key encapsulation RFC?

I try to use below RFC algorithm in my app: https://www.rfc-editor.org/rfc/rfc5990

Bouncy Castle for c# and java supports it but I am working on iOS. As I know best tools for cryptography in ios is commoncrypto library. So the question is that whether this library supports it or not?

I do not find any usefull information on documentation and hope someone here can help.

Solution

  • I don't see any references to it, but it should be relatively easy to implement this yourself. You can follow the code of Bouncy and implement using the misnamed SecKeyEncrypt with kSecPaddingNone. The KDF's used (KDF2 and 3) are rather simple as well.

    So although I don't usually recommend implementing crypto functions, this one is relatively safe to implement as the underlying primitives are provided by the platform.
