Cryptography Services for Windows Embedded CE-based devices provide services that enable application developers to add security to applications using cryptography. It includes functionality for encoding to and decoding from ASN.1, for hashing, encrypting, and decrypting data, for using digital certificate, and for managing certificates.
Windows Embedded CE 6.0 Cryptography Services with High Encryption Provider is FIPS 140-2, level 1 certified. For more information about FIPS certification for Windows Embedded CE 6.0, see this Web site. For more information about FIPS certification for Windows CE 5.0, see this Web site.
