Generate Openssl Key Without Password

15-09-2021
 |  [RAND-100] - Comments

An RSA key is a private key based on RSA algorithm, used for authentication and an symmetric key exchange during establishment of an SSL/TLS session. The RSA private key in PEM format (the most common format for X.509 certificates, CSRs and cryptographic keys) can be generated from the command line using the openssl genpkey utility. Make a new ssl private key:. Generate a new unencrypted rsa private key in PEM format: openssl genrsa -out privkey.pem 2048. You can create an encrypted key by adding the -des3 option. # To make a self-signed certificate:. Create a certificate signing request (CSR) using your rsa private key: openssl req -new -key privkey.pem -out certreq.csr. root@centos8-1 # yum -y install openssl. Create encrypted password file (Optional) With openssl self signed certificate you can generate private key with and without passphrase. If you use any type of encryption while creating private key then you will have to provide passphrase every time you try to access private key. The generated private key has no password: how can I add one during the generation process? Note: take into account that my final goal is to generate a p12 file by combining the certificate provided according to the CSR and the private key (secured with a password).

This is take straight from http://devsec.org/info/ssl-cert.html. I’m getting it on my blog, as a reference to myself, so I can make a key pair quickly in the future.

Make a new ssl private key:

Write down the Common Name (CN) for your SSL Certificate. The CN is the fully qualified.

* Generate a new unencrypted rsa private key in PEM format:

openssl genrsa -out privkey.pem 2048

You can create an encrypted key by adding the -des3 option.

#
To make a self-signed certificate:

* Create a certificate signing request (CSR) using your rsa private key:

openssl req -new -key privkey.pem -out certreq.csr

( This is also the type of CSR you would create to send to a root CA for them to sign for you. )

* Self-sign your CSR with your own private key:

openssl x509 -req -in certreq.csr -signkey privkey.pem -out newcert.pem

I am generating exporting some pkcs#12 files for testing purposes. These files are not being used in production and only exist temporary during automated testing.

I am using the following command:

Why is it insisting on an export password when I have included -nodes?

My OpenSSL version is OpenSSL 1.0.1f 6 Jan 2014 on Ubuntu Server 14.10 64-bit.

In interactive mode, when it prompts for a password, just press enter and there will be no password set.

If you are want to automate that (for example as an ansible command), use the -passout argument. It expects the parameter to be in the form pass:mypassword. Since we want no password:

Base64 encode/decode issue

Generate

openssl,hex,base64,ocaml

openssl is writing the base64 text with embedded newlines every 64 chars. That means that your input to echo -n inside decode_base64 has newlines in it. This gives you the 'Unterminated quoted string' message. This is a crazy way to be doing base64 encoding in OCaml anyway. Check out https://github.com/mirage/ocaml-base64...

To link a static library into a shared library on x86_64, the static library needs to be compiled with -fPIC. You could now build OpenSSL manually with -fPIC set, but that'd be a bit of a hassle. I'd suggest to configure Qt with -openssl instead of -openssl-linked. Then SSL won't...

Should I BIO_flush() after BIO_read()-ing?

openssl,base64,decode,flush,decoder

You don't need to. BIO_flush tells the writer that there's no more data coming, so it can write the equals signs at the end to pad out the result, if necessary. You don't need this when reading.

What you describe is the traditional API model for using OpenSSL. An SSL object owns the socket and performs all I/O on it, so you have to use the SSL_read() and SSL_write() functions when performing secure I/O. OpenSSL also has a newer API model using BIO structures instead. You can...
