PSA_KEY_TYPE_DES macro

Key for a cipher or MAC algorithm based on DES or 3DES (Triple-DES). The size of the key can be 64 bits (single DES), 128 bits (2-key 3DES) or 192 bits (3-key 3DES). Note that single DES and 2-key 3DES are weak and strongly deprecated and should only be used to decrypt legacy data. 3-key 3DES is weak and deprecated and should only be used in legacy protocols.
