"openssl des3" is really "openssl enc -des3". The password-based key derivation is a custom, undocumented scheme which, as far as password-based key derivation schemes go, is quite weak; see this answer (especially at the end) for some details. Basically, this is equivalent to hashing the password with a couple of MD5 invocations.

2014年12月5日 · If the OpenSSL configuration file is defined well, then we could use -config myopenssl.cnf without the need of -reqexts param. First, you would need to create an OpenSSL configuration file {your_name}.cnf. For example, nano myopenssl.cnf. Below is a template OpenSSL configuration file

2013年4月24日 · The OpenSSL FIPS Object Module is a specific subset of OpenSSL, API-compatible with OpenSSL, and provided as source code. That module has gone through the long and painful administrative process of obtaining a FIPS 140-2 validation.

While the OpenSSL project was busy missing the OpenSSL 3 release date by several years, firing multiple project managers in the process, the LibreSSL developers have started to replace large swaths of the OpenSSL codebase with new ISC-licensed code, while maintaining compatibility with the majority of OpenSSL 1.0 and 1.1 APIs.

2024年12月17日 · While analyzing the handshake process in TLS 1.3 and comparing it to TLS 1.2, I began to wonder if the simplified handshake structure in TLS 1.3 introduces new vulnerabilities.

2022年11月6日 · However, you asked about using openssl to do AES encryption using GCM mode, not CBC mode. Unfortunately, this is not possible with the command line interface for openssl, because AES-GCM is not supported.

2014年10月15日 · Stack Exchange Network. Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.

2014年4月15日 · What is the difference between these openssl commands: "openssl genrsa" "openssl genpkey" "openssl req -newkey rsa:bits [everything else]" Which one should I be using when preparing a new CSR?

2019年12月12日 · OpenSSL can take CA certificates from a file and or/directory. There are standard locations build into the library but an application can also specify alternative locations. With s_client this can be done using the -CApath directory and -CAfile file arguments. A certificate file (-CAfile) contains a list of CA certificates in PEM format.
