I am doing this for encrypting the data:

select keytbl
REPLACE ALL lickey WITH Encrypt(lickey, lcEncryptPassword)

**********************************************
I am doing this to decrypt the same from the table:

lcLicKeyEncrypted = LOOKUP(keytbl.lickey,1,keytbl.id)
SET LIBRARY to mapppath+"cipher50.fll" ADDI
lcLicKey = decrypt(lcLicKeyEncrypted , lcEncryptPassword)

***********************************************

another thing is Encrypt is appearing in blue.

Decrypt is not appearing in blue. (In the source code window).
