[xmlsec] KeyDataKlass implementation

[P.Q.Hung]

Hi, We 'd like to make xmlsec to use our own crypto framework. After reading the following comment from xmlsec documentation: "The key data implementation should implement at least one of xmlRead or binRead methods." These are my thoughts:   xmlRead/Write are necessary for reading/writing key-material from/to xml document during signing/verifying. OpenSSL, MSCrypto, implemented only these methods.   binRead/Write are necessary for reading/writing key materials from/to binary file.   My question: If I implement only these binRead/Write methods, DOES xmlsec core know how to write key-info do xmlSig?   thanks a lot -- P.Q.Hung
