NAME
certmgr - Mono Certificate Manager (CLI version)
SYNOPSIS
certmgr [action] [object type] [options] store [filename] or certmgr -ssl [options] url
DESCRIPTION
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.
STORES
The store represents the certificate store to use. It can be one of the following:
My This is the personal certificate store.
AddressBook
This is the store for other people.
CA This is a store for intermediate certificate authorities.
Trust This is for trusted roots.
Disallowed
This is for untrusted roots
ACTIONS
-list List the certificates, CTL or CTL in the specified store.
-add Add a certificate, CRL or CTL to specified store. If filename it's a pkcs12 or pfx file, and it
contains a private key, it will be imported to local key pair container.
-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
store.
-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).
-importKey
Allows importing a private key from a pkcs12 file into a local key pair store. (Usefull when you
already have the key's corresponding certificate installed at the specific store.)
OBJECT TYPES
-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 encoding.
-ctl Add, Delete or Put certificate trust lists (CRL). UNSUPPORTED.
OPTIONS
-m Use the machine's certificate stores (instead of the default user's stores).
-v More details displayed on the console.
-p password
Use the specify password when accessing a pkcs12 file.
-help , -h , -? , /?
Display help about this tool.
FILES
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 ~/.config/.mono/certs/
For example the trusted root certificates for a user would be kept under
~/.config/.mono/certs/Trust/
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).
Private key data is stored under
~/.config/.mono/keypairs/
EXAMPLES
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: FFA3AC0084DA1673B5A031EBB2156B3E8FBBF6D8
mono certmgr.exe -del -c -m Trust FFA3AC0084DA1673B5A031EBB2156B3E8FBBF6D8
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 www.verisign.com.
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).
KNOWN ISSUES
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.
