In depth

A closer look at CryptoPunk

CryptoPunk uses the Diffie-Hellman protocol on points of an elliptical curve over a finite field for its public-key exchange. The algorithm uses two LFSRs, three XOR blocks, three ADD blocks, one MUL block, and two PCBC feedback links into the LFSRs' tap function.

In addition, you can import and export public keys, and shred selected files.
