Encryption

JISAM supports the encryption of the data file. The encryption is activated by the WITH ENCRYPTION clause in FILE-CONTROL.

An example of encrypted file:

select arc assign to "arc"        organization indexed        with encryption        record arc-k.

The data is encrypted using a key provided through the configuration. The configuration property iscobol.file.encryption.key must be set to a value different from spaces, otherwise a file mismatch error is raised.

If an encrypted file is opened for input or i-o with the wrong encryption key, then a file corrupt error is raised.

If the encryption key is not set in the configuration, opening an encrypted file produces a 9X status.
