CryptoAPI is the API set that enables developers to add security that is based on cryptography to applications. CryptoAPI includes functionality for encoding to and decoding from ASN.1, encrypting and decrypting data, authentication using digital certificates, and digital certificate management using certificate stores. CryptoAPI supports both PKI and symmetric key cryptography.

CryptoAPI for Windows CE 5.0 fulfills the requirements for Federal Information Processing Standard (FIPS). For more information, see FIPS Compliance.
