# cert-sync(1)

Mono Certificate Store Sync Tool

## NAME

cert-sync - Mono Certificate Store Sync Tool

## SYNOPSIS

**cert-sync \[--quiet\] \[--user\] filename**

## DESCRIPTION

This tool allows you to populate a Mono certificate store, from a large  concatenated list of certificates in PEM format (commonly provided on most  Linux distributions).

Its use is intended to be automated at Mono install time, by distribution  packagers, to seamlessly provide SSL support to Mono applications without  further user interaction.

## OPTIONS

- *--quiet*

  Suppress verbose output

- *--user*

  Populate the per-user store in the user's home directory, instead of the  system-wide store.

- *filename.crt*

  Path to a certificate bundle. The Mono store will have any extra entries  removed, and new entries added, to reflect the provided file.

## EXAMPLES

- **cert-sync /etc/ssl/certs/ca-certificates.crt**

  Synchronize the machine store, from the Debian cert store location

- **cert-sync --user /etc/pki/tls/certs/ca-bundle.crt**

  Synchronize the user store, from the Red Hat cert store location
