Crypto API

Hello all!

Could someone provide a useful example of how to use cryptography? For example I have some signed XML and I want to get certificate from it (public key). It has embedded PEM-encoded certificate, so I saved it to some file and tried to open it with crypto-fuctions but without luck.
The code below:

   CryptoManager = New CryptoManager("", "", 1);
   CertFile = New TextReader("C:\Users\Intel\Downloads\certtest.txt");
   CertBase64String = CertFile.Read(); 
   StringFunctionsClientServer.NormalizeString(CertBase64String);
   CertBinaryData = Base64Value(CertBase64String);
   Cert = CryptoManager.GetCertificatesFromSignature(CertBinaryData);

NormalizeString function deletes every whitespace or CR+LF to make sure only base64 string is present.

Hello, Alexey.

This is not trivial.

Try using openssl. Maybe something like this will help:

openssl x509 -in full.cer -pubkey -noout | openssl enc -base64 -d > public.der
