Abstract
A method and a system for encryption of a data element in a relational database, wherein each data element includes a string of at least one character. The method includes the steps of: reading the type of a data element which is to be encrypted; interpreting the data type to form a restricting character set for each character of the data element; and encrypting each character of the data element into an encrypted character selected from the restricting character set.
