openssl is an open-source command-line tool that is commonly used for various cryptographic operations, including creating private keys, generating certificates, and encrypting/decrypting data. It is a versatile tool that is widely used in the security and encryption domain.
openssl is commonly used to create Certificate Signing Requests (CSRs) which are used to request SSL/TLS certificates from Certificate Authorities. It is also used to install SSL/TLS certificates on servers to enable secure communication over HTTPS.
openssl can be used to verify the information contained in digital certificates, such as the certificate issuer, expiration date, and subject information. This verification process helps ensure the authenticity and validity of the certificates being used in secure communications.
