[[ Check that a certificate matches a private key or certificate request ]]

== General OpenSSL Commands ==
'''Convert certificates from one type to another''' 
'''PEM to DER''' 
:openssl x509 -in cert.crt -outform der -out cert.der 

'''DER to PEM''' 
:openssl x509 -in cert.crt -inform der -outform pem -out cert.pem 

'''View Certificate Revocation List''' 
:openssl crl -noout -text -in example.crl ( PEM encoded ) 
:openssl crl -inform DER -noout -text -in example.crl ( DER encoded ) 

The below commands allow you to generate CSRs, Certificates, Private Keys and do other miscellaneous tasks. 
'''Generate a new private key and Certificate Signing Request''' 
:openssl req -out CSR.csr -new -newkey rsa:2048 -nodes -keyout privateKey.key 
'''Generate a self-signed certificate ''' 
:openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout privateKey.key -out certificate.crt 
'''Generate a certificate signing request (CSR) for an existing private key''' 
:openssl req -out CSR.csr -key privateKey.key -new 
'''Generate a certificate signing request based on an existing certificate.''' 
:openssl x509 -x509toreq -in certificate.crt -out CSR.csr -signkey privateKey.key 

'''Calculating sha-1 fingerprint ''' 
:openssl x509 -noout -in idp_blabla_ac_uk.crt -fingerprint -sha1 

'''Calculating SHA-256 fingerprint''' 
:openssl x509 -noout -fingerprint -sha256 -in filename.crt 

'''Remove a passphrase from a private key''' 
openssl rsa -in privateKey.pem -out newPrivateKey.pem 

'''Checking Using OpenSSL'''

If you need to check the information within a Certificate, CSR or Private Key, use these commands. You can also check CSRs and check certificates using our online tools. 

:'''Check a Certificate Signing Request (CSR)'''
:openssl req -text -noout -verify -in CSR.csr 

:'''Check a private key''' 
:openssl rsa -in privateKey.key -check 

:'''Check a certificate''' 
:openssl x509 -in certificate.crt -text -noout 

:'''Check a PKCS#12 file (.pfx or .p12)''' 
:openssl pkcs12 -info -in keyStore.p12

:'''Check the fingerprint of a certificate.''' 
::'''Get SHA-1 fingerprint:''' 
::::openssl x509 -noout -in certificate.pem -fingerprint -sha1 

::'''Get SHA-256 fingerprint:''' 
::::openssl x509 -noout -in certificate.pem -fingerprint -sha256 

'''You can check if an SSL certificate matches a Private Key by using the 2 easy commands below. '''
::::'''For your SSL certificate:''' openssl x509 -noout -modulus -in <file>.crt | openssl md5 
::::'''For your RSA private key:''' openssl rsa -noout -modulus -in <file>.key | openssl md5 

'''Debugging Using OpenSSL''' 

If you are receiving an error that the private doesn't match the certificate or that a certificate that you installed to a site is not trusted, try one of these commands. If you are trying to verify that an SSL certificate is installed correctly, be sure to check out the SSL Checker. 

'''Check an MD5 hash of the public key to ensure that it matches with what is in a CSR or private key''' 

openssl x509 -noout -modulus -in certificate.crt | openssl md5 
openssl rsa -noout -modulus -in privateKey.key | openssl md5 
openssl req -noout -modulus -in CSR.csr | openssl md5 

'''Check an SSL connection. All the certificates (including Intermediates) should be displayed''' 

openssl s_client -connect www.paypal.com:443 

'''Converting Using OpenSSL''' 

These commands allow you to convert certificates and keys to different formats to make them compatible with specific types of servers or software. For example, you can convert a normal PEM file that would work with Apache to a PFX (PKCS#12) file and use it with Tomcat or IIS. Use our SSL Converter to convert certificates without messing with OpenSSL. 

'''Convert a DER file (.crt .cer .der) to PEM''' 

openssl x509 -inform der -in certificate.cer -out certificate.pem 
'''
Convert a PEM file to DER''' 
openssl x509 -outform der -in certificate.pem -out certificate.der 

'''Convert a PKCS#12 file (.pfx .p12) containing a private key and certificates to PEM''' 

openssl pkcs12 -in keyStore.pfx -out keyStore.pem -nodes 

You can add -nocerts to only output the private key or add -nokeys to only output the certificates. 

'''Convert a PEM certificate file and a private key to PKCS#12 (.pfx .p12)''' 
openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile CACert.crt 

'''Diagnosing server certificate problems''' 
When testing, beware that most modern browsers will automatically download intermediate certificates if your server fails to supply them so it can be difficult to tell if you have got things right for any that won't. One way to double-check is to use the 'openssl s_client' command to inspect the certificates being returned by a web server: 

openssl s_client -connect <server>:<port> -showcerts 

Replacing <server> and <port> appropriately (<port> probably needs to be 443). This actually establishes a connection to the server - you can terminate it by typing ctrl-d or similar. The message "unable to get local issuer certificate" just means that your local openSSL doesn't have, or hasn't been configured to find, an appropriate root certificate for the chain presented. 
This isn't necessarily a problem with the server - if you care, research s_client's -CApath and -CAfile options. 
What is important is that your certificate and the appropriate two chaining certificates appear in the output.

[[ an example ]] 
'''
openssl s_client -connect hostname.of.server:636''' 

'''Encrypt and Decrypt File'''
To encrypt files with OpenSSL is as simple as encrypting messages. The only difference is that instead of the echo command we use the -in option with the actual file we would like to encrypt and -out option, which will instruct OpenSSL to store the encrypted file under a given name: 

$ openssl enc -aes-256-cbc -in /etc/services -out services.dat 

To decrypt back our services file use: 

$ openssl enc -aes-256-cbc -d -in services.dat > services.txt 
enter aes-256-cbc decryption password: 

'''Extracting Certificate and Private Key Files from a .pfx File''' 
<source lang="text">
Procedure
To extract all certificates from a pfx file and save in text file:
openssl pkcs12 -nodes -in the_pfx_file.pfx > thekeys.txt

Take the file you exported (e.g. certname.pfx) and copy it to a system where you have OpenSSL installed. Note: the *.pfx file is in PKCS#12 format and includes both the certificate and the private key.
Run the following command to export the private key: openssl pkcs12 -in certname.pfx -nocerts -out key.pem -nodes
Run the following command to export the certificate: openssl pkcs12 -in certname.pfx -nokeys -out cert.pem
Run the following command to remove the passphrase from the private key: openssl rsa -in key.pem -out server.key
</source>

'''Create a .pfx file from certificate and private key:'''
<source lang="text">
openssl pkcs12 -export -out domain.name.pfx -inkey domain.name.key -in domain.name.crt

Steps: 
1. Needs mysql connection, create database and credentials. 
2. For the tomcat app create a web.xml file with entries for the API app: 
[[the_web_xml_for_tomcat|The web.xml file]] 
3. Two java files are used 
[[The_Api.java_file|Api.java]]

<servlet-name>controller</servlet-name>
<description>
This servlet plays the "controller" role in the MVC architecture
used in this application. It is generally mapped to the ".do"
filename extension with a servlet-mapping element, and all form
submits in the app will be submitted to a request URI like
"saveCustomer.do", which will therefore be mapped to this servlet.

The initialization parameter names for this servlet are the
"servlet path" that will be received by this servlet (after the
filename extension is removed). The corresponding value is the
name of the action class that will be used to process this request.

# A POST request to the API
response = requests.post(url, json=data)

Create a router with Almalinux 8

2024-11-02T22:55:19Z

George2:

Task goal: to create a Vagrant and ansible build which will create a router based on Almalinux 
in Windo
1. Use Vagrant to build a vm with Virtualbox
2. Use ansible to perform the configuration

These are separate tasks as Virtualbox is running in Windows and Anible does not run in Windows.

# The most common configuration options are documented and commented below.

# Create a forwarded port mapping which allows access to a specific port
# within the machine from a port on the host machine. In the example below,
# accessing "localhost:8080" will access port 80 on the guest machine.
# NOTE: This will enable public access to the opened port
# config.vm.network "forwarded_port", guest: 80, host: 8080

# # Customize the amount of memory on the VM:
# vb.memory = "1024"

# View the documentation for the provider you are using for more

# Enable provisioning with a shell script. Additional provisioners such as
# Ansible, Chef, Docker, Puppet and Salt are also available. Please see the
