According to https://tls.mbed.org/kb/cryptography/asn1-key-structures-in- der-and-pem

Pem are Base64 encoded, maybe I should do something like that :

socket.SSLCertificate(LoadFile(Base64Decode(GetDataFile("C:\\Users\\Xemuth\\Documents\\ssl\\chain.pem"))),
		      LoadFile(Base64Decode( GetDataFile("C:\\Users\\Xemuth\\Documents\\ssl\\privkey.pem"))),
		      true);

It don't work, I will try to find other way of decoding it

EDIT : I have try to decode my certificate using this website : https://lapo.it/asn1js/ and it work :
This page contains a JavaScript generic ASN.1 parser that can decode any valid ASN.1 DER or BER structure whether Base64-encoded (raw base64, PEM armoring and begin-base64 are recognized) or Hex-encoded.

Do Upp ASN1 parser is able to reconize and decode multiple structure of pem ?
