encryption - JCE - Java 7...? -


i've installed jdk 7. contains following jars:

local_policy us_export_policy

but when start application, facing jce error. googled , downloaded jdk 7 jce here.

my doubt is, when jdk 7 has jce jars, why should download same jce jars , replace existing jce jars again..??

edit:

i using ssha encryption.

log:

java.security.invalidkeyexception: illegal key size java.lang.illegalstateexception: cipher not initialized

the downloaded files not the same.

basically named .jar files contain property files enable/disable cryptography functions. because of several different export/import regulations in different countries.

you modify files , enable/disable cryptography functions application.
