WRITE CRYPT.DATA ON

FILE.VAR, REC.KEY

DISPLAY.DECRYPTED

SENTRY.ENCRYPT = "*SENTRY.ENCRYPT"

READ THE.RECORD FROM FILE.VAR,

REC.KEY ELSE ...

THE.KEY = "Fudge Tastes Good!"

CALL @SENTRY.ENCRYPT(THE.RECORD,

OUT.DATA, THE.KEY)

PRINT OUT.DATA

It is critical that the encryption key be a constant. Without the key, decryption of encrypted data is not possible. If an incorrect key is used with encrypted data, the data is re-encrypted and will now require two decryptions to be made readable. For example, suppose that data were encrypted three times with different keys as follows:

CALL @SENTRY.ENCRYPT(ORIG.DATA, ENCRYPT.DATA, KEYA)

CALL @SENTRY.ENCRYPT(ENCRYPT.DATA, MUDDLED.DATA, KEYB)

CALL @SENTRY.ENCRYPT(MUDDLED.DATA, GARBLED.DATA, KEYC)

To decrypt GARBLED.DATA we'd have to call SENTRY.ENCRYPT three times as follows:

CALL @SENTRY.ENCRYPT(GARBLED.DATA, TEMP.DATA, KEYC)

CALL @SENTRY.ENCRYPT(TEMP.DATA, TEMP.DATA2, KEYB)

CALL @SENTRY.ENCRYPT(TEMP.DATA2, ORIG.DATA, KEYA)

NOTICE: Be extremely careful when you use encryption. Test thoroughly and on a comprehensive set of data. Once data are encrypted using your own private encryption key, we know of NO technique to decrypt the data should you overwrite, forget, lose, or destroy the original key. You are completely responsible for your use of this subroutine. It's POWERFUL and potentially dangerous.

Subroutine: SENTRY.USER.ITEM.CONTROL

SENTRY.USER.ITEM.CONTROL is a subroutine used to determine access rights of a user ID to items defined by the user with the SENTRY User Item Maintenance Screen (Section 2-6).

Sample:

SENTRY.USER.ITEM.CONTROL = "*SENTRY.USER.ITEM.CONTROL"
