Open. SSL Command- Line HOWTOOpen. SSL Command- Line HOWTOThe openssl application that ships with the Open. SSL libraries can perform a wide range of crypto operations. This HOWTO provides some cookbook- style recipes for using it.

It can come in handy in scripts or for. Documentation for using the openssl application is somewhat scattered. I assume that you’ve already got a functional Open.

SSL installation. PATH. Just to be clear, this article is strictly practical; it does not. If you don’t know what an MD5. The nature of this article is that I’ll be adding new examples. Check back at a later date if I haven’t gotten to the. How do I find out what Open.

The. best thing to do is provide an invalid command (help or - h will do. The. ciphers(1) man page is. TLSv. 1 ciphers. openssl ciphers - v - tls. HIGH'. # list only high encryption ciphers using the AES algorithm. AES+HIGH'. Benchmarking. How do I benchmark my system’s performance?

The Open. SSL developers have built a benchmarking suite directly into the. It’s accessible via the speed option. It tests how. many operations it can perform in a given time, rather than how long it.

This strikes me as quite. To run a catchall benchmark, run it without any further options.

The. downside, however, is that you’ll have to either store the passphrase in. It violates my normally paranoid nature to say it, but I prefer.

I don’t have to manually type a passphrase each. The. certificate will be valid for 3. Using this command- line invocation, you’ll have to answer a lot of.

Country Name, State, City, and so on. The tricky question is. Common Name.” You’ll want to answer with the hostname or CNAME by. This is very important.

If your. web server’s real hostname is mybox. Common Name” question. Once you’re comfortable with the answers you provide to those questions. I’ve. included some information about location into the example that follows. CN). openssl req \.

C=US/ST=Oregon/L=Portland/CN=www. How do I generate a certificate request for Veri. Sign? Applying for a certificate signed by a recognized certificate authority. Veri. Sign is a complex bureaucratic process. You’ve got to perform.

As in the recipe for creating a self- signed certificate. The recipe below assumes you don’t. You’ll end up with two. If you’ve already got a key and would like to use it for. Similarly, you can also provide subject information on the command line. CN=www. mydom. com/O=My Dom, Inc./C=US/ST=Oregon/L=Portland' \.

When dealing with an institution like Veri. Sign, you need to take special. I know from personal. Organization Name will stall the process. If you’d like, you can double check the signature and information. Save the key file in a secure location.

You’ll need it in order to use. Veri. Sign sends you. The certificate request will. Veri. Sign’s online application form. How do I test a new certificate? The s. By default, the server will listen on port 4. Don’t forget to specify the “https”.

You should see a page listing the. The x. 50. 9 subcommand is. The examples below all. Using the - text option will give you the full breadth of information. Other options will provide more targeted sets of data.# who issued the cert? They are often associated with the file.

To create a PKCS#1. During the conversion process, you’ll be given an. Export Password” (which can be empty, if you. PKCS#1. 2 file, mycert.

Certificates. are typically issued for a limited period of time—usually just one. Unless you. make an exception, Open. SSL won’t verify a.

What certificate authorities does Open. SSL recognize? When Open. SSL was built for your system, it was configured with a. Directory for Open. SSL files.” (That’s the - -openssldir option passed. This is the directory.

The default location for this directory is /usr/local/ssl, but most. Red Hat/Fedora). /etc/ssl (Gentoo), /usr/lib/ssl (Debian), or.

System/Library/Open. SSL (Macintosh OS X). Use the version option to identify which directory (labeled.

OPENSSLDIR) your installation uses. Within that directory and a subdirectory called certs, you’re likely. A large file called cert. Veri. Sign. and Thawte. Some small files in the certs subdirectory named with a . CA. Some symlinks in the certs subdirectory with obscure filenames.

There is typically one of these links for each. The first part of obscure filename is actually a hash value based on. The file. extension is just an iterator, since it’s theoretically possible. On my Gentoo system, for example, there’s a symlink named. Sure enough. the certificate in that file generates a hash the equates to the. When an application encounters a remote certificate, it will typically.

If found, the certificate. It’s interesting to note that some applications, like Sendmail, allow. Pine, do not. How do I get Open. SSL to recognize/verify a certificate? Put the file that contains the certificate you’d like to trust into the. Then create the. hash- based symlink.

Here’s a little script that’ll do just that.#!/bin/sh. There are other examples. In this section, I assume you are familiar with the specific protocols. SMTP, HTTP, etc. Explaining them is out of the scope of this. How do I connect to a secure SMTP server? You can test, or even use, an SSL- enabled SMTP server from the command. Some time around the 0.

When using SNI, the client. TLS negotiation. As of the date of this writing. TLS with SMTP servers, so you have. SSL connections with any other protocol.# https: HTTP over SSL.

If you need a production- quality. Stunnel instead. The s. Pages will be. # resolved relative to the current directory. I’ve seen several. Open. SSL. page does not accurately report the digest functions available via. I suggest running openssl dgst - h to. MD5 digest. openssl dgst - md.

SHA2. 56 digest. openssl dgst - sha. The MD5 digests are identical to those created with the widely available. The following example assumes that you want to sign the.

SHA2. 56 sum of a file called foo- 1. How do I verify a signed digest? To verify a signed digest you’ll need the file from which the digest was. How do I create an Apache digest password entry?

Apache’s HTTP digest authentication feature requires a special password. Apache ships with the htdigest utility, but it will only write. When working with remote users, it’s. The format of the password database is relatively simple: a. Apache Auth. Name directive), and an MD5 digest of those two items and. Below is a script that duplicates the output of. It. takes advantage of the dgst option’s ability to read from standard.

Consider using its - n option if you want to avoid that. Still, you may have occasion to want to. All you want to have to remember is a password. It can nearly. be that simple—if you can also remember the cipher you employed for.

To choose a cipher, consult the enc(1) man. More simply (and. Cipher commands' heading. After you choose a cipher, you’ll also have to decide if you want to.

Doing so will mean the encrypted data can be. Otherwise, the output will be a. AES in CBC mode. openssl enc - aes- 2. To decrypt file. enc you or the file’s recipient will need to remember. If you’d like to avoid typing a passphrase every time you encrypt or.

PASS PHRASE ARGUMENTS.” The format of the password argument is. Silly. Password. # provide password in a file. Errors. How do I interpret SSL error messages? Poking through your system logs, you see some error messages that are.

Open. SSL or crypto. The code number is found between. In this case, it’s 0. A. In this example. RSA. After that, of course.
