WebAug 21, 2012 · From a crypto standpoint, there's not much point to encrypting something with the private key; after all, the public key is just that: public. If anyone can decrypt it (No OS provides any protection of public keys, so it's trivial to get a copy), there's not much point in encrypting it. To sign an assembly with a strong name, you must have a public/private key pair. This public and private cryptographic key pair is used during compilation to create a strong-named assembly. You can create a key pair using the Strong Name tool (Sn.exe). Key pair files usually have an .snk extension. See more •Create and use strong-named assemblies See more clawes carpets clifton

WebDec 8, 2024 · Static-ephemeral is a bit different: here the encryptor generates a temporary (ephemeral) EC key pair. He then uses this key pair together with the receiver's public key to generate a secret key which can be used to encrypt the data. Finally, he sends the public key of the ephemeral key pair to the receiver together with the encrypted data.
