Sample for calculate a session key with curve25519 #16

Closed raffoschi closed 4 years ago

Hello,

I'm new with CryptoLib4Pascal and I can't find an example to obtain a session key using curve25519.

With a partial pascal porting of tweet-nacl (https://github.com/krisztianpinter/curve25519-delphi), A and B set their keys with something like pubKey_A:=crypto_scalarmult_base(privKey_A) and pubKey_B:= crypto_scalarmult_base(privKey_B).

Next A and B calculate the common session key with sessionKey:=crypto_scalarmult(privKey_A,pubKey_B) and sessionKey:=crypto_scalarmult(privKey_B,pubKey_A)

I looked at UsageExamples but I can't figure out how to do something similar.

Thanks and Regards Raffaele

Just found that there are other examples than those in UsageExamples. Thank you anyway
