OpenSSL is a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It is also a general-purpose cryptography library. For more information about the team and community around the project, or to start making your own contributions, start with the community page. Install a one version (openssl-1.0.2d-fips-2.0.10) found in SourceForge but it does not generate the files correctly. There is also the official website, but I do not know how to install it and how, so that when it comes to generating the keys and.pem file, it works. OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j). View Analysis Description.
Pre-compiled 64-bit (x64) and 32-bit (x86) 1.1.1 executables and libraries for Microsoft Windows Operating Systems with a dependency on the Microsoft Visual Studio 2015-2019 runtime. The distribution may be used standalone or integrated into any Windows application. OpenSSL 1.1.1k is now available, including bug and security fixes Read the full changelog OpenSSL is a development tool designed to implement the SSL and TLS cryptographic protocols in your.
OpenSSL is the gold standard for online encryption and with this package, developers can implement SSL and TLS encryption within their applications.
As the Internet has turned towards more security and encryption, it's absolutely important to take encryption into consideration when performing any types of tasks or data transfer online. With OpenSSL, you've got a reliable and community-supported approach to data encryption.
The main library issued by this includes a Windows command line application with access to all of the ciphers and algorithms that Open SSL supports.
The application can also generate personal and public keys using SHA256, SHA-1, MD5, base64, Camellia, Blowfish, AES and a long list of others. Public key support includes Diffie-Hellman, RSA and DSA key exchanges.
As an open source project, OpenSSL will continue to grow when more participants join the project.
The OpenSSL library uses the included full-strength general-purpose cryptography library, which can be used by itself.

The openssl command, which is included in the
openssl package, allows you to perform various cryptography functions from the OpenSSL library including:
Creating and managing pairs of private and public keys.
Performing public key cryptographic operations.
Creating self-signed certificates.
Creating certificate signing requests (CSRs).
Creating certificate revocation lists (CRLs).
Converting certificate files between various formats.
Calculating message digests.
Encrypting and decrypting files.
Testing both client-side and server-side TLS/SSL with HTTP and SMTP servers.
Verifying, encrypting and signing S/MIME email.
Generating and testing prime numbers, and generating pseudo-random data.
The following are some sample openssl commands.
Create a self-signed X.509 certificate that is valid for 365 days, writing the unencrypted private key to
prikey.pem and the certificate to
Test a self-signed certificate by launching a server that listens on port 443.
Test the client side of a connection. This command returns information about the connection including the certificate, and allows you to directly input HTTP commands.
Convert a root certificate to a form that can be published on a web site for downloading by a browser.
Extract a certificate from a server.
Display the information contained in an X.509 certificate.
Display the SHA1 fingerprint of a certificate.
Generate a CSR, writing the unencrypted private key to
prikey.pem and the request to
csr.pem for submission to a CA. The CA signs and returns a certificate or a certificate chain that authenticates your public key.
Display the information contained in a CSR.
Verify a certificate including the signing authority, signing chain, and period of validity.
Display the directory that holds information about the CAs trusted by your system. By default, this directory is
/etc/pki/tls/certs subdirectory contains trusted certificates.
Create an SHA1 digest of a file.
Sign the SHA1 digest of a file using the private key stored in the file
Verify the signed digest for a file using the public key stored in the file
List all available ciphers.
Encrypt a file using Blowfish.
Decrypt a Blowfish-encrypted file.
Convert a base 64 encoded certificate (also referred to as PEM or RFC 1421) to binary DER format.
Convert the base 64 encoded certificates for an entity and its CA to a single PKCS7 format certificate.
