The Mode class defines the encryption mode types supported by TDGSS. The Mode attribute values shown in the Quality of Protection (QOP) must appear on this list.

If you use Java Cryptography Extensions (JCE), the mode types must match the mode types supported by TDGSS.
Mode Type Description
NONE Encryption not enabled
CBC Cipher-block Chaining

An operational mode for a block cipher, in which a set number of bits is encrypted as a single unit or block with a cipher key applied to the entire block.

CFB Ciphertext Feedback

An operational mode for block cipher, in which plaintext values are encrypted and transferred one at a time.

ECB Electronic Code Book

An operational mode for a block cipher in which each possible block of plaintext has a defined corresponding ciphertext value.

For compatibility with pre-14.0 Teradata Database releases only.

OFB Output Feedback

An operational mode for a block cipher that permits encryption of differing block sizes, but the output of the encryption block function is the feedback instead of the cipher text.

For compatibility with pre-14.0 Teradata Database releases only.

This list of supported modes does not change unless you install a new release of TDGSS that supports a different set of encryption modes.
