1. Description

Add extension to the CREATE-FILE command to enable file encryption.

Encryption arguments are as follows:

    ENCRYPTED=TRUE
    ALGORITHM=<<algorithm>>
    KEY=<<decrypt key>>

Supported file types:

    j4, HASH4, HASHP (jPlus), UD

Supported encryption algorithms:

    RC2, BASE64, DES, 3DES, BLOWFISH, AES

Encryption modes:

    Default: use internal encryption             : ENCRYPTED=TRUE
    User: Use a defined method and key : ENCRYPTED=TRUE ALGORITHM=xxx KEY=yyy

e.g.

    CREATE-FILE TEST ENCRYPTED=TRUE ALGORITHM=BLOWFISH KEY=12344567889  1 1
    CREATE-FILE TEST ENCRYPTED=TRUE  1 1

2. Previous Release Behavior

N/A

3. Current Release Behavior

You can opt to use the default encryption method and internal encryption key by not specifying any algorithm or key:

    CREATE-FILE TEST ENCRYPTED=TRUE  1 1
    * If UD file types are used,  the flags to say this file is encrypted are stored in the directory in the [.jbase_header] record,  deleting this will stop the file from decrypting.

Optionally specify your own:

    CREATE-FILE TEST ENCRYPTED=TRUE ALGORITHM=BLOWFISH KEY=12344567889  1 1

If user specifies their own key, an encrypted version is stored in the ]K file, the above example will generate:

    TEST
    TEST]D
    TEST]K

• no data in the file or dictionary can be decrypted without the ]K file being accessible.

• key files have to be used with the file they where created with.
