Encrypt sensitive passwords in shell script - Which one do you prefer ?

I am looking for various options to encrypt a sensitive password in a unix shell script. After a bit of googling, I learned about 'shc'. Can you please advice on what things you use for this purpose, if any ?

My requirement / idea is

A .sql file will have to be executed by a shell script in SQLPLUS as USER/XXXX . The .sql file will be prepared by developer and will be put to a directory to which their osuser - say 'user1' will have write access. I will have 'oracle' user in the server , who is the DBA user. I want them to run this SQL like, runthis.sh test.sql where runthis.sh is owned by oracle user and will reside in some directory owned by DBA user. I am planning to configure schema password (USER/XXXX) in runthis.sh , which a developer is not supposed to know.
But if I give execute permission for 'user1' to runthis.sh, it becomes readable and all can read the password. Is there anyway , I can store encrypted password in SQLPLUS connect string in this file / encrypt shell script as such ?

Thanks in Advance.  

With Regards,
Sreejith
