Manage certificates

VisualCron can handle standard X509 certificates. These can be stored at the server location and be available for reuse in Tasks like the Email Task. You reach Manage certificates from the Main menu->Manage.

The main window of Manage certificates lets you view currently stored Certificates and their properties.

Importing a certificate

You can currently import certificates from files with the following format:

You import certificates by clicking the Import tool button. Remember to change the file filter to see your particular certificate file format.

Exporting a certificate

You can export in the following formats:

You export certificates by clicking the Export tool button. Change file filter to change file saving format.

Generate a certificate

To start the Generate certificate wizard click on the Generate tool button.

Select type of certificate (currently only Self-signed certificate).

Hash algorithm

Use this property to get or set algorithm that will be used for hash calculation.

Public key strength

Use this property to control the strength of the public key in bits.

Enter subject info for the certificate. Remember to set the Email property if you are going to use the Certificate in the Email Task.

Enter validity period for the certificate.

Last step. Click on Next to generate Certificate.

Delete a certificate

Select a certificate row and click on the Delete tool button.

Certificate file formats supported by VisualCron

PFX (PKCS#12): Binary file format, which allows storing of one or more certificates and associated private keys in one file in encrypted form. The keys are encrypted with password. Microsoft's implementation of PFX loader doesn't support TripleDES encryption, so you need to care about this issue when you save the certificate for further use with Microsoft software.

PEM: Certificate and private key format, which includes base64-encoded DER data and optional text headers , enclosed into special begin and end marks. Private keys can be encrypted using DES (tripleDES) agorithm. Certificate and key can be saved to one file. The file can even contain several certificates and keys. PEM format is used by OpenSSL package.

SPC: Binary file format, which allows storing of certificates only (no private keys). Several certificates can be saved in one file. Private keys are usually saved to a separate file in DER or PVK format. Some implementations encode the PKCS#7 format to base64 text encoding (and sometimes even with UTF16), but this is not standard-compliant.

PVK: Binary file format for storing private keys with password-based encryption.

CER/DER/KEY: Basic certificate and key format, which represents pure certificate and key data in binary ASN.1 notation. Certificates and keys are stored separately. Some implementations encode the DER format to base64 text encoding (and sometimes even with UTF16), but this is not standard-compliant.
