uCrypt SDK by Cypherbridge Systems is a comprehensive cryptographic software development kit that implements commercial grade and high-strength Suite B cryptographic algorithms. It is designed to add electronic data privacy, authentication, and integrity to products. The SDK provides a wide range of cryptographic capabilities, including various ciphers, hashes, PKCS/PKIX operations, and RFC standard operations. It supports AES, ECC, RSA, and includes X.509 certificate processing with RSA and ECDSA key handling. uCrypt SDK is a compact ANSI C software library optimized for small and medium memory models, efficiently utilizing CPU, RAM, and flash resources. It employs a nonthreaded, run-to-completion synchronous execution for cryptographic operations. The SDK is integrated with the SDKPac product family and is used as part of the uFile File Based Encryption solution for protecting data-at-rest.
