Official Step-By-Step guide
1. Before you begin, note the following information about running KYRTool & OpenSSL
If you have a command line parameter with spaces in it, such as the path to a file, the space can cause the command line to be read incorrectly, resulting in errors. This can affect running commands for both OpenSSL and KYRTool
To include a space in a parameter, the parameter must be delimited with quotation marks. For example, if Notes were installed in the Program Files directory, then the command line for creating a keyring might look like this:
kyrtool =”c:\Program Files\IBM\Notes\notes.ini” create -k “c:\Program Files\IBM\Notes\data\keyring.kyr” -p password
1a. KYRTool
Place the KYRTool in the Notes program directory, as it relies on .DLLs installed by Notes.
If you have the Notes/Domino program directory in your system’s PATH environment variable, this can be installed to any directory.
1b. OpenSSL
Download links for the Windows versions of OpenSSL are available at https://slproweb.com/products/Win32OpenSSL.html
The light version of OpenSSL is sufficient for the tasks required for creating a SHA-2 certificate. v1.0.1j is the latest recommended release as of December 2014. Either the 32-bit or 64-bit version can be used if you are on Windows 7.
OpenSSL may need updates to Windows Visual C++ libraries. If the libraries are not up to date, a prompt will display during the OpenSSL install noting that updated Visual C++ libraries are needed. Links for downloading these libraries are also on the download page for OpenSSL.
A configuration file “openssl.cfg” will be extracted by the installer to the bin directory. In order for OpenSSL to read this configuration file, you must set an environment variable by running the following command from a DOS prompt
SET OPENSSL_CONF=\openssl.cfg
e.g. SET OPENSSL_CONF=c:\OpenSSL-Win64\bin\openssl.cfg
You run OpenSSL from the “openssl.exe” file, which is found in the \bin directory of the OpenSSL install. Open a command prompt window in this directory to run it. If you double click on openssl.exe, it will open in a DOS command window. If you launch OpenSSL this way, you enter only the name of the OpenSSL function in the command window. For example, instead of typing “openssl genrsa…” you would enter “genrsa…”
2. Generate an RSA keypair using OpenSSL
[~]$ openssl genrsa -out server.key 4096
Generating RSA private key, 4096 bit long modulus
…………………………………………………………………………….++
………………………………………………………….++
e is 65537 (0x10001)
The resulting keypair should not be password protected. This isn’t a good security practice, so only perform these steps for production systems on a restricted access system believed to be secure. The resulting keypair should look like the following:
[C:\] type server.key
—–BEGIN RSA PRIVATE KEY—–

—–END RSA PRIVATE KEY—–
3. Generate a Certificate Signing Request (CSR) using OpenSSL
NOTE: If a config file for OpenSSL is not defined by an environment variable, a user may not be able to create a csr with the “openssl req” command, and will receive the following message when running the command. “Unable to load config info from /usr/local/ssl/openssl.cnf”. See Step 1b above to resolve this.
This step prompts you for information that should be in your final certificate, bundles that up along with the public half of the RSA keypair that was just generated, and signs the whole thing with the private half of the keypair. In this example, everything was left blank except for the DNS name of the SSL test server. Note the “-sha256”, as the default algorithm for current versions of OpenSSL is SHA-1.
[~]$ openssl req -new -sha256 -key server.key -out server.csr
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter ‘.’, the field will be left blank.
—–
Country Name (2 letter code) [XX]:.
State or Province Name (full name) []:
Locality Name (eg, city) [Default City]:.
Organization Name (eg, company) [Default Company Ltd]:.
Organizational Unit Name (eg, section) []:.
Common Name (eg, your name or your server’s hostname) []:www.example.com
Email Address []:
Please enter the following ‘extra’ attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
[C:\] type server.csr

—–END CERTIFICATE REQUEST—–
4. Acquire an SSL/TLS certificate from a third party CA
This process varies from CA to CA, but you generally copy the certificate request block from above into a web form and pick what signing algorithm you would like the CA to use. Feel free to select one of the SHA-2 algorithms (SHA-256, SHA-384, and SHA-512) — the resulting keyring file will work just fine on any 9.0.x server, even those without the hotfix for TLS and SHA-2.
You will receive a certificate just like the one created in the self-signed steps. This can be displayed by using the “type” command from a command prompt or by opening the file in Notepad.
[C:\] type server.pem
—–BEGIN CERTIFICATE—–
MIIEyjCCArICCQCIqzNZtkev6TANBgkqhkiG9w0BAQUFADAnMSUwIwYDVQQDDBx1

—–END CERTIFICATE—–
You may also receive some of the CA’s intermediate root certificates. Also note that the file received may be a .crt instead of .pem. The .crt file will act the same as a .pem when you display it.
5. Create a new keyring file
At this point in the example, the Administrator switched from the Linux box where OpenSSL was run to a Windows box to use kyrtool.exe.
[C:\] kyrtool =c:\lotus\notes\notes.ini create -k c:\lotus\notes\data\keyring.kyr -p password
Keyfile c:\lotus\notes\data\keyring.kyr created successfully
2 [C:\Lotus\Notes\Data] dir keyring*
Volume in drive C is C_Drive
Volume Serial Number is 306D-00D5
Directory of C:\Lotus\Notes\Data
10/08/2014 02:15 PM 29,161 keyring.kyr
10/08/2014 02:15 PM 129 keyring.sth
2 File(s) 29,290 bytes
0 Dir(s) 400,743,673,856 bytes free
6. Import the RSA keypair and self-signed certificate into the new keyring file
6a. Concatenate server.key and server.pem into a single file:
This step varies from the self-signed case. You will have more than one certificate in your “.pem” file, and will want to place them in order with your server’s SSL “leaf” certificate first and the root certificate last. Verify step 6b will check to ensure that the ordering is correct. If it returns any warnings or errors, edit the PEM file and verify it again.
Note the following:
Certificate Authorities will frequently return a signed certificate in a .crt file. If they also provide the root certificates when returning the CSR file, then you can concatenate all of the .crt files to the private key by using the “type” command from a DOS prompt.
The files should be concatenated with the server key first, the server’s cert next, the intermediate cert next, and the root cert last. Concatenation can be done from a DOS prompt using the TYPE command. The type command takes a list of files, and appends them together into an output file designated with a greater-than symbol. For example, type server.key server.crt intermediate.crt root.crt > server.txt In this example “server.txt” is the file provided to the kyrtool for import into a Domino keyring. You can display this output file in Notepad.
If the root and intermediate certs are not provided with the signed certificate, export the intermediate and root certificates by opening the server certificate with Windows Crypto Extensions. This will display the server in a three-tabbed user interface. On the third tab, select each of the signing certificates, select display, and then export that certificate using the “save to file” command on the second tab. Save each cert file using Base 64 format.
6b. Verify the Input file:
This is an example of a complete and correctly ordered PEM file:
[C:\] kyrtool =c:\lotus\notes\notes.ini verify c:\lotus\notes\data\ssl\server.txt
KyrTool v1.0
Successfully read 2048 bit RSA private key
INFO: Successfully read 4 certificates
INFO: Private key matches leaf certificate
INFO: IssuerName of cert 0 matches the SubjectName of cert 1
INFO: IssuerName of cert 1 matches the SubjectName of cert 2
INFO: IssuerName of cert 2 matches the SubjectName of cert 3
INFO: Final certificate in chain is self-signed
If you receive any ERROR: lines, you should resolve those errors before moving on to step 6c.
6c. Import the keypair and self-signed certificate:
[C:\] kyrtool =c:\lotus\notes\notes.ini import all -k c:\lotus\notes\data\keyring.kyr -i c:\lotus\notes\data\ssl\server.txt
Using keyring path ‘c:\lotus\notes\data\keyring.kyr’
Successfully read 4096 bit RSA private key
SECIssUpdateKeyringPrivateKey succeeded
SECIssUpdateKeyringLeafCert succeeded
7. Examine the resulting keyring file
[C:\] kyrtool =c:\lotus\notes\notes.ini show keys -k c:\lotus\notes\data\keyring.kyr
[C:\] kyrtool =c:\lotus\notes\notes.ini show certs -k c:\lotus\notes\data\keyring.kyr
8. Copy over your new keyring file and start the Domino server
Back up your old .kyr and .sth files, shut down the server, copy over your new keyring and stash files, restart the server, and check out the results!
