NAME
certmgr - Mono Certificate Manager (CLI version)
SYNOPSIS
certmgr [action] [object type] [options] store [filename] or certmgr
-ssl [options] url
DESCRIPTION
This tool allows to list, add, remove or extract certificates, certifi-
cate 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 is
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 assumes a 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 and any other intermediate
certificates in the IntermediateCA store).
-importKey
Allows importing a private key from a pkcs12 file into a local
key pair store. (Useful when you already have the key's corre-
sponding certificate installed at the specific store.)
OBJECT TYPES
-c , -cert , -certificate
Add, Delete or Put certificates. That is the specified file
must/will contain X.509 certificates in DER binary encoding.
-crl Add, Delete or Put certificate revocation lists (CRL). That is
the specified file must/will contain X.509 CRL in DER binary en-
coding.
-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 specified 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 be-
tween 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 ~/.con-
fig/.mono/certs/
For example the trusted root certificates for a user would be kept un-
der
~/.config/.mono/certs/Trust/
Certificates files are kept in DER (binary) format (extension .cer).
The filenames either start 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 dis-
play 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 re-
stricted. The following error message will appear if the current
user doesn't have the minimum access rights to remove the cer-
tificate: 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.
