Cisco ISE Password encryption scheme on CSV export

[wredelijkheid]

Cisco ISE has the option to export the local user accounts to a CSV file. Passwords in that file are encrypted with a password which is entered upon export.
Now I want to create my own import files, but these need to contain the encrypted passwords (part of an automation process), and not the plain text versions. To do that I need to know which encryption scheme is used to created these encrypted passwords, so I can use this in the creation of the CSV files..

The following is test data I used to export, but I can’t figure out the (OpenSSL?/GPG?) encryption settings
User password = 1q2w3e4r5t6y7u8i9o0p
ISE Export/Import Password = 1234567890
Encrypted password in resulting CSV = m2VgunDTWtMt187knQGIUnvcZXr1Ld+uGMg3QKuqbGI=

Anyone got any info on that?

Did you figure this out? The "encrypted" string is base64, which you can then pipe into openssl... but I've had no luck yet finding the correct combination.

For anyone who finds this, the following does NOT work, all error with bad magic number.
