Class StaticValueDbCryptCallbackSpi

  • All Implemented Interfaces:

    public final class StaticValueDbCryptCallbackSpi
    extends java.lang.Object
    implements DbCryptCallbackSpi
    Provider for a static value response database encryption callback.

    This provider takes the dbCryptConfig value to determine the static value of the response:

    • value is null: empty response
    • value starts with "base64:": rest of the value is decoded to bytes using base64
    • all other values are encoded to bytes using UTF-8

      • getDbCryptCallbackName

        public java.lang.String getDbCryptCallbackName()
        Description copied from interface: DbCryptCallbackSpi
        Name of the database encryption callback.

        This name is for identification and selection purposes. As the name will be used in connection properties, we suggest to use relatively simple/short names, but make sure it is unique enough to prevent name conflicts. Consider using something like <company-or-author>.<name>.

      • createDbCryptCallback

        public DbCryptCallback createDbCryptCallback​(java.lang.String dbCryptConfig)
        Description copied from interface: DbCryptCallbackSpi
        Creates the database encryption callback with a configuration string.

        The configuration string of the dbCryptConfig connection property is plugin specific, but we suggest the following conventions:

        • For binary data, use prefix base64: to indicate the rest of the string is base64-encoded
        • Avoid use of &, ; or :, or 'hide' this by using base64 encoding; this is necessary to avoid existing limitations in the parsing of connection properties that are added directly to the URL (we hope to address this in the future), and to allow support for other prefixes similar to base64:
