Client certificates and keys: This will create the mike-laptop.crt and mike-laptop.key files in the keys directory.
  2. Generating a Unique Encryption Key. If you generate new versions of the key file, the system appends the new version of the key to the end of the key file. To invoke the command on a Windows server, change to the directory where PSCipher resides and enter.

I wouldn't generate a new keypair for each user. A single server keypair would suffice. Distribute the public key with your application and keep the private key on your server. Use RSA not to encrypt your login data, but to negotiate an AES key, and then use that to encrypt your data.

I think 'close to a minute' is far too optimistic for the time required :-( -- note that the prime for DH is supposed to be a safe prime.

You can contrast

which generates 2048-bit Diffie-Hellman parameters, to

which generates a 4096-bit RSA key (containing two 2048-bit primes) and note that the second is dramatically faster than the first. On-the-fly DH parameter generation is really slow.

However, generating 1024-bit parameters is probably fast enough to do on launch or install. Under the authors' estimates this might be fairly safe today because the adversary will have to spend many millions of dollars to attack your individual service (and you could change the parameters once a day or something if you wanted). But I think the authors agreed that large predistributed parameters make a better tradeoff for most cases.

There is an RFC about to issue listing such parameters

Edit: I possibly shouldn't refer to 'the authors' in the third person here, because you are the lead author.

Further edit: 'Close to a minute' is actually not a bad estimate, but the variance is very high! So it can easily be considerably worse.

Encryption Key Generator

You use the PSCipher Java utility's buildkey command to build new Triple DES encryptionkeys. The buildkey command adds anew Triple DES encryption key stored in the psvault file (the keyfile). If you generate new versions of the key file, the system appendsthe new version of the key to the end of the key file.

To invoke the command on a Windows server, changeto the directory where PSCipher resides and enter: Filemaker server 16 license key generator.

To invoke the command on UNIX, change to the directorywhere PSCipher resides and enter:

Select one web server in your system to generatethe new version of the key file. The pscipher.bat and PSCipher.shutilities only run in the Java environment of the web server. Afteryou have created the new key file, you then copy the new version ofpsvault from the initial server to the appropriate directories onall the appropriate servers in your system. The psvault file is storedin different directories depending on your web server vender (as describedin the following sections). On the application server the psvaultfile resides in <PS_HOME>secvault.

Note: If you are not using the default encryption keyand you have generated a unique encryption key, note that each timeyou add a new server to your system, you will need to copy the keyfile to the appropriate location on that server. For example, if youare using the default key version ({V1.1}), any server you add tothe system and install PeopleTools on will also have the default keyversion ({V1.1}). As such, no further steps are required. However,if you have generated a new key, giving the version number a valueof {V1.2} or greater, then you need to make sure to copy that keyfile to the added server(s). Also, each time you update the key, youneed to ensure that the new version of the key file is copied to theadditional servers in your system.

Warning! When you upgrade to new PeopleTools releases, asin PeopleTools 8.48 to PeopleTools 8.50, you will need to backup anymodifications you have made to the key file using PSCipher in theprevious release and reapply that same key file to the appropriateservers onto which you have installed the new PeopleTools release.
