FireDaemon OpenSSL provides a wide range of cryptographic functions, including symmetric encryption, public-key encryption, message digest and hash functions, digital signatures, and random number generation. It supports a large number of cryptographic algorithms, such as AES, RSA, SHA, and many others. In addition to cryptographic functions, OpenSSL also provides utilities for generating and managing digital certificates and keys, creating and verifying digital signatures, and performing SSL/TLS handshake and negotiation.nIt is used by many software applications (including FireDaemon Certify One, FireDaemon Fusion, and FireDaemon Lozenge) web servers, and security products, and is an important component of many security-related systems and services.
