DomainKeys Public/Private Key-pair Generation |
| DomainKeys Public/Private Key-pair Generation |
Last Updated: July 9, 2005 |
Command Line Tools Available |
|
Perhaps the easiest way to generate DomainKeys public/private key-pairs is to use the CPAN command line tools available. The tool can create a key-pair, and format them for DNS publication. |
Generating a private-key for the MTA |
|
For ease of explanation, the openssl command is used throughout this document to describe the mechanism by which keys are managed.
One way to generate a 768 bit private-key suitable for DomainKeys, is to use openssl like this:
$ openssl genrsa -out rsa.private 768
Which results in the file rsa.private containing the key information
similar to this:
-----BEGIN RSA PRIVATE KEY-----
MIIByQIBAAJhAKJ2lzDLZ8XlVambQfMXn3LRGKOD5o6lMIgulclWjZwP56LRqdg5

-----END RSA PRIVATE KEY-----
This private key will be inserted into your DomainKeys-enabled MTA. Your MTA or plugin should provide instructions on how to do so.
|
Generating the public-key for the DNS selector record |
|
To extract the public-key component from the private-key, use openssl like this:
$ openssl rsa -in rsa.private -out rsa.public -pubout -outform PEM
Which results in the file rsa.public containing the key information similar to this:
-----BEGIN PUBLIC KEY-----
MHwwDQYJKoZIhvcNAQEBBQADawAwaAJhAKJ2lzDLZ8XlVambQfMXn3LRGKOD5o6l
MIgulclWjZwP56LRqdg5ZX15bhc/GsvW8xW/R5Sh1NnkJNyL/cqY1a+GzzL47t7E
XzVc+nRLWT1kwTvFNGIoAUsFUq+J6+OprwIDAQAB
-----END PUBLIC KEY-----
This public-key data is placed in the selector's DNS record as the value of p. Thus, a selector's record may look like:
k=rsa; t=y; p=MHwwDQYJKoZIhvcNAQEBBQADawAwaAJhAKJ2lzDLZ8XlVambQfMXn3LRGKOD5o6l MIgulclWjZwP56LRqdg5ZX15bhc/GsvW8xW/R5Sh1NnkJNyL/cqY1a+GzzL47t7E XzVc+nRLWT1kwTvFNGIoAUsFUq+J6+OprwIDAQAB; |
