mode (property)
Specifies the symmetric cipher mode of operation.
Syntax
@property (nonatomic,readwrite,assign,getter=mode,setter=setMode:) int mode; - (int)mode; - (void)setMode:(int)newMode;
/* Possible Values */
SCM_DEFAULT(0),
SCM_ECB(1),
SCM_CBC(2),
SCM_CTR(3),
SCM_CFB8(4),
SCM_GCM(5),
SCM_CCM(6),
SCM_POLY_1305(7)

}Default Value
0
Remarks
Use this property to specify the mode of operation as required by your environment. The defaultsetting is CBC.
| scmDefault | 0 | The default mode in current circumstances. |
| scmECB | 1 | ECB (electronic code book) mode. This is insecure, unless you know how to use it right. |
| scmCBC | 2 | CBC (cipher block chaining mode) |
| scmCTR | 3 | Counter mode |
| scmCFB8 | 4 | Cipher feedback mode |
| scmGCM | 5 | Galois counter mode |
| scmCCM | 6 | CCM mode |
