hi,

We have encrypted a value in java using des3 with a specific key.  We have converted this byte array to
a base64 encoded string value.

Now we want to decrypt this data using des3 in oracle.
To do this do we
1) convert String to raw value using UTL_RAW.CAST_TO_RAW(base64String)
2) Decode base 64 raw value using UTL_DECODE.BASE64_ENCODE
3) Decrypt using des3 oracle passing in key, and value returned from 2.
4) Convert to varchar2 using UTL_RAW.CAST_TO_VARCHAR2

I think you should explore what DBMS_OBFUSCATION_TOOLKIT package offers to you.

it has DBMS_OBFUSCATION_TOOLKIT.DECRYPT() procedures , overloading procedures to decipher the byte array encoded using JAva DES3 algorithm
