openssl dgst -sha1 -sign privateKey.pem -out signature1 someInputFile The following commands also generates a signature for an input file: openssl dgst -binary -sha1 someInputFile > digest openssl rsautl -sign -in digest -inkey privateKey.pem -out signature2 As far as I know, they should both create the RSA signature of a SHA1 digest of the file.
The DER format is simply a binary form of a certificate instead of the ASCII PEM format. It sometimes has a file extension of .der but it often has a file extension of .cer so the only way to tell the difference between a DER .cer file and a PEM .cer file is to open it in a text editor and look for the BEGIN/END statements. I am trying to convert a file containing a binary key hash to base64 using openssl. The command I am using is as follows: openssl base64 -in sha.txt > debug_base64.txt sha.txt holds the binary string. When I execute this in command line (in C:\openssl\bin) I get the Windows pop-up telling me openssl.exe has stopeed working. The OpenSSL project does not distribute any code in binary form, and does not officially recommend any specific binary distributions. An informal list of third party products can be found on the wiki.Some third parties provide OpenSSL compatible engines. OpenSSL source is maintained by a team of committers. The overall project is run by the OpenSSL Management Committee. Technical decisions are made by the OpenSSL Technical Committee. We operate under a set of project bylaws and ask everyone to follow our code of conduct The OpenSSL project does not distribute the toolkit in binary form. However, for a large variety of operating systems precompiled versions of the OpenSSL toolkit are available. In particular on Linux and other Unix operating systems it is normally recommended to link against the precompiled shared libraries provided by the distributor or vendor. OpenSSL: Convert DER to PEM. openssl x509 -in cert.der -out cert.pem. You can also use similar commands to convert PEM files to these different types of files as well. Furthermore, there are additional parameters you can specify in your command — such as -inform and -outform — but the above examples are the basic, bare bones OpenSSL commands. I personally found this to be specific to the OpenSSL binary in use. On my system using msys2/mingw64 I've noticed that two different OpenSSL binaries are present, for example:

Jul 25, 2020 · OpenSSL on Windows If you’re using Windows, you can install one of the many OpenSSL open-source implementations: the one we can recommend is Win32 OpenSSL by Shining Light Production, available as a light or full version, both compiled in x86 (32-bit) and x64 (64-bit) modes.
Jul 02, 2020 · OpenSSL is a commercial-grade tool developed under an Apache-style license. It is a full-featured cryptography & SSL / TLS toolkit commonly used to create certificate signing requests needed by a certificate authority (CA). OpenSSL can create private keys, sign certificates, generate certificate signing requests (CSR), and much more.
