## AcquireAESInfo AcquireAESInfo() allocate the AESInfo structure. The format of the AcquireAESInfo method is:
      AESInfo *AcquireAESInfo(void)
## DecipherImage DecipherImage() converts cipher pixels to plain pixels. The format of the DecipherImage method is:
      MagickBooleanType DecipherImage(Image *image,const char *passphrase,
        ExceptionInfo *exception)
A description of each parameter follows: ##### image the image. ##### passphrase decipher cipher pixels with this passphrase. ##### exception return any errors or warnings in this structure. ## DestroyAESInfo DestroyAESInfo() zeros memory associated with the AESInfo structure. The format of the DestroyAESInfo method is:
      AESInfo *DestroyAESInfo(AESInfo *aes_info)
A description of each parameter follows: ##### aes_info the cipher context. ## EncipherImage EncipherImage() converts pixels to cipher-pixels. The format of the EncipherImage method is:
      MagickBooleanType EncipherImage(Image *image,const char *passphrase,
        ExceptionInfo *exception)
A description of each parameter follows: ##### image the image. ##### passphrase encipher pixels with this passphrase. ##### exception return any errors or warnings in this structure. ## EncipherAESBlock EncipherAESBlock() enciphers a single block of plaintext to produce a block of ciphertext. The format of the EncipherAESBlock method is:
      void EncipherAES(AESInfo *aes_info,const unsigned char *plaintext,
        unsigned char *ciphertext)
A description of each parameter follows: ##### aes_info the cipher context. ##### plaintext the plain text. ##### ciphertext the cipher text. ## SetAESKey SetAESKey() sets the key for the AES cipher. The key length is specified in bits. Valid values are 128, 192, or 256 requiring a key buffer length in bytes of 16, 24, and 32 respectively. The format of the SetAESKey method is:
      SetAESKey(AESInfo *aes_info,const StringInfo *key)
A description of each parameter follows: ##### aes_info the cipher context. ##### key the key. |
