 * \defgroup CryptoIMPL Cryptographic Functions Implementation
 * @brief Implementations for \ref CryptoAPI
 *
 * CryptoIMPL provides implementation of cryptographic functions to encrypt and decrypt data, to generate keys and
 * initialization vectors, and to compute digests.
 *
 * The reference implementation uses OpenSSL library, but can be extended to use platform-specific APIs.
