In FreeMind, the whole map or single branches may be encrypted. An encrypted branch has a padlock icon. Encryption is available since FreeMind 0.8.0.
Encryption algorithm
The encryption algorith used in FreeMind is Triple DES or DES, depending on JRE version[TODO]. Both are symmetric-key algorithms built in Java.
For details, search for "PBEWithMD5AndTripleDES".
Troubleshooting
Problem: Maps encrypted with FreeMind running on Java Runtime Environment JRE 1.4 cannot be opened with FreeMind running on Java Runtime Environment JRE 1.6.
Solution: A provisional solution is to stick with Java Runtime Environment JRE 1.4. (Or even 1.5? TODO)
Detail: There is a bug in the PBE key getkey.getAlgorithm() method in JRE 1.4> key.getAlgorithm() returns PBEWithMD5AndDES instead of PBEWithMD5AndDES.
