OpenSSL Generate 4096-bit Certificate (Public/Private Key Encryption) with SHA256 Fingerprint
Openssl P12 To Crt
- Using OpenSSL, this is what you would do: $ openssl req -out codesigning.csr -key private.key -new Where private.key is the existing private key. As you can see you do not generate this CSR from your certificate (public key). Also you do not generate the 'same' CSR, just a new one to request a new certificate.
- Steps to create RSA key, self-signed certificates, keystore, and truststore for a server. Generate a private RSA key. Openssl genrsa -out diagserverCA.key 2048 Create a x509 certificate. Openssl req -x509 -new -nodes -key diagserverCA.key -sha256 -days 1024 -out diagserverCA.pem.
- Digital certificates are an integral part of any public key infrastructure (PKI). Openssl pkcs12 -info -in test.p12. Code signing certificates are the least common to create and by far are the most expensive to generate if you are using an external CA and will be selling your software. If the intent is to sell your developed software.
/morphvox-license-key-generator-mac.html. Create a pkcs12 (.pfx or.p12) from OpenSSL files (.pem,.cer,.crt.) You have a private key file in an openssl format and have received your SSL certificate. You'd like now to create a PKCS12 (or.pfx) to import your certificate in an other software? Here is the procedure! $ openssl pkey -in private-key.pem -out public-key.pem -pubout You may once again view the key details, using a slightly different command this time. $ openssl pkey -in public-key.pem -pubin -text The output for the public key will be shorter, as it carries much less information, and it will look something like this.
gencert.sh
| # Generate Private Key and Certificate using RSA 256 encryption (4096-bit key) |
| openssl req -x509 -newkey rsa:4096 -keyout privatekey.pem -out certificate.pem -days 365 |
| # Alternatively, setting the '-newkey' parameter to 'rsa:2048' will generate a 2048-bit key. |
| # Generate PKCS#12 (P12) file for cert; combines both key and certificate together |
| openssl pkcs12 -export -inkey privatekey.pem -in certificate.pem -out cert.pfx |
| # Generate SHA256 Fingerprint for Certificate and export to a file |
| openssl x509 -noout -fingerprint -sha256 -inform pem -in certificate.pem >> fingerprint.txt |
| # Generate SHA1 Fingerprint for Certificate and export to a file |
| #openssl x509 -noout -fingerprint -sha1 -inform pem -in certificate.pem >> fingerprint.txt |
| # FYI, it's best practice to use SHA256 instead of SHA1 for better security, but this shows how to do it if you REALLY need to. |

- This module allows one to (re-)generate PKCS#12.
The below requirements are needed on the host that executes this module.
- python-pyOpenSSL
| Parameter | Choices/Defaults | Comments |
|---|---|---|
| action string |
| export or parse a PKCS#12. |
| attributes string | The attributes the resulting file or directory should have. To get supported flags look at the man page for chattr on the target system. This string should contain the attributes in the same order as the one displayed by lsattr. The = operator is assumed as default, otherwise + or - operators need to be included in the string. | |
| backup added in 2.8 |
| Create a backup file including a timestamp so you can get the original output file back if you overwrote it with a new one by accident. |
| certificate_path path | The path to read certificates and private keys from. | |
| force |
| Should the file be regenerated even if it already exists. |
| friendly_name string | Specifies the friendly name for the certificate and private key. | |
| group | Name of the group that should own the file/directory, as would be fed to chown. | |
| iter_size integer | Default: | Number of times to repeat the encryption step. |
| maciter_size integer | Default: | Number of times to repeat the MAC step. |
| mode string | The permissions the resulting file or directory should have. For those used to /usr/bin/chmod remember that modes are actually octal numbers. You must either add a leading zero so that Ansible's YAML parser knows it is an octal number (like 0644 or 01777) or quote it (like '644' or '1777') so Ansible receives a string and can do its own conversion from string into number.Giving Ansible a number without following one of these rules will end up with a decimal number which will have unexpected results. As of Ansible 1.8, the mode may be specified as a symbolic mode (for example, u+rwx or u=rw,g=r,o=r).As of Ansible 2.6, the mode may also be the special string preserve.When set to preserve the file will be given the same permissions as the source file. | |
| other_certificates list / elements=path | List of other certificates to include. Pre 2.8 this parameter was called ca_certificates | |
| owner | Name of the user that should own the file/directory, as would be fed to chown. | |
| passphrase string | ||
| path | Filename to write the PKCS#12 file to. | |
| privatekey_passphrase string | Passphrase source to decrypt any input private keys with. | |
| privatekey_path path | ||
| selevel | Default: 's0' | This is the MLS/MCS attribute, sometimes known as the range.When set to _default, it will use the level portion of the policy if available. |
| serole string | When set to _default, it will use the role portion of the policy if available. | |
| setype string | When set to _default, it will use the type portion of the policy if available. | |
| seuser string | By default it uses the system policy, where applicable.When set to _default, it will use the user portion of the policy if available. | |
| src path | ||
| state |
| Whether the file should exist or not. All parameters except path are ignored when state is absent. |
| unsafe_writes boolean |
| Influence when to use atomic operation to prevent data corruption or inconsistent reads from the target file. By default this module uses atomic operations to prevent data corruption or inconsistent reads from the target files, but sometimes systems are configured or just broken in ways that prevent this. One example is docker mounted files, which cannot be updated atomically from inside the container and can only be written in an unsafe manner. This option allows Ansible to fall back to unsafe methods of updating files when atomic operations fail (however, it doesn't force Ansible to perform unsafe writes). IMPORTANT! Unsafe writes are subject to race conditions and can lead to data corruption. |
