Crypto chips
Embeddable cryptographic processors

Below is a non-exhaustive overview of cryptographic processors, also known as crypto chips. Some chips contain a single encryption algorithm and were developed for a specific application or device, whilst others are more universal and may by found various cryptographic products.
