Use Asymmetric Key Cryptography

Asymmetric key encryption requires the generation of a public and private key, allowing the message to be encrypted with a "public" key but only decrypted using a "private" key.

Generate an asymmetric key pair.

In[1]:=

keys = GenerateAsymmetricKeyPair[]

Out[1]=

Encrypt the message using the public key.

In[2]:=

encrypted = Encrypt[keys["PublicKey"], "The gold is located off the coast of Honduras."]

Out[2]=

The message cannot be decrypted using the public key that encrypted it. The private key must be used.

In[3]:=

Decrypt[keys["PublicKey"], encrypted]

Out[3]=

In[4]:=

Decrypt[keys["PrivateKey"], encrypted]

Out[4]=
