Another possibility: It is a Base36 encoding of the SHA-256 hash of a phrase. For instance, the SHA-256 hash of "hello world" in hex is b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9 . Converting that hex to Base36 would give a shorter string, but it would include uppercase letters? Actually, Base36 is case-insensitive by convention, but often represented in lowercase. It’s plausible.
