certmgr - Mono Certificate Manager (CLI version)
certmgr [action] [object type] [options] store [filename] or certmgr
-ssl [options] url
This tool allow to list, add, remove or extract certificates,
certificate revocation lists (CRL) or certificate trust lists (CTL)
to/from a certificate store. Certificate stores are used to build and
validate certificate chains for Authenticode(r) code signing validation
and SSL server certificates.
-list List the certificates, CTL or CTL in the specified store.
-add Add a certificate, CRL or CTL to specified store.
-del Remove a certificate, CRL or CTL from specified store. You must
specify the object to be removed with it's hash value (and not a
filename). This hash value is shown when doing a -list on the
-put Copy a certificate, CRL or CTL from a store to a file.
-ssl Download and add the certificates from a SSL session. You'll be
asked to confirm the addition of every certificate received from
the server. Note that SSL/TLS protocols do not requires a server
to send the root certificate. This action assume an certificate
(-c) object type and will import the certificates in appropriate
stores (i.e. server certificate in the OtherPeople store, the
root certificate in the Trust store, any other intermediate
certificates in the IntermediateCA store).
-c , -cert , -certificate
Add, Delete or Put certificates. That is the specified file
must/will contains X.509 certificates in DER binary encoding.
-crl Add, Delete or Put certificate revocation lists (CRL). That is
the specified file must/will contains X.509 CRL in DER binary
-ctl Add, Delete or Put certificate trust lists (CRL). UNSUPPORTED.
-m Use the machine's certificate stores (instead of the default
-v More details displayed on the console.
-help , -h , -? , /?

WARNING: This details the current behavior of Mono and could change
between releases. The only safe way to interact with certificate
stores is to use the certmgr tool. The current releases of Mono keeps
all the user certificate stores in separates directories under
For example the trusted root certificates for a user would be kept
Certificates files are kept in DER (binary) format (extension .cer).
The filenames either starts with
tbp (thumbprint) or ski (subject key identifier).
The rest of the filename is the base64-encoded value (tbp or ski).
mono certmgr.exe -list -c -m Trust
List all certificates in the machine Trust store. This will
display the hash value for each certificate. This value can be
used to identify uniquely a certificate for some operations
(e.g. delete). E.g. Unique Hash:
mono certmgr.exe -del -c -m Trust
Remove the certificate, represented by the hash value, from the
machine Trust store. Note that the machine store is normally
restricted. The following error message will appear if the
current user doesn't have the minimum access rights to remove
the certificate: Access to the machine 'Trust' certificate store
has been denied.
certmgr -ssl https://www.verisign.com
Import certificates from www.verisign.com used for HTTP over
SSL. See KNOWN ISSUES (MD2) if you're downloading from
certmgr -ssl ldaps://www.nldap.com:636
Import the certificates from www.nldap.com used for secure LDAP.
This works even if we don't know how to speak LDAP because we
stop the communication shortly after the SSL handshake (which
gives us the certificate).
MD2 Some Certificate Authorities (CA) old root certificates use the
MD2 hash algorithm. MD2 is old enough not to be part of the
standard .NET framework. This makes it impossible to validate a
digital signature made with MD2. For this reason MD2 is included
in the Mono.Security.dll assembly. However the machine.config
file must be updated so the OID for MD2 is known at runtime.
To correct this insert the following XML snippet inside the
<configuration> element of your machine.config file.
<nameEntry name="MD2" class="monoMD2" />
<oidEntry OID="1.2.840.113549.2.2" name="MD2" />
