AESDecryptECB

Decrypts byte data stream by using the AES algorithm in the ECB mode (deprecated).

Syntax

IppStatus ippsAESDecryptECB(const Ipp8u* pSrc, Ipp8u* pDst, int srclen, const IppsAESSpec* pCtx);

Include Files

ippcp.h

Parameters

pSrc

Pointer to the input ciphertext data stream of variable length.

pDst

Pointer to the resulting plaintext data stream of variable length.

srclen

Length of the ciphertext data stream in bytes.

pCtx

Pointer to the IppsAESSpec context.

Description

Note

The ECB functionality remains in the library, but it is not safe when used as is. Use any other mode, for example CBC.

The function decrypts the input data stream of a variable length according to the ECB mode as specified in [NIST SP 800-38A].

Return Values

ippStsNoErr

Indicates no error. Any other value indicates an error or warning.

ippStsNullPtrErr

Indicates an error condition if any of the specified pointers is NULL.

ippStsLengthErr

Indicates an error condition if the output data stream length is less than or equal to zero.

ippStsContextMatchErr

Indicates an error condition if the context parameter does not match the operation.

ippStsUnderRunErr

Indicates an error condition if srclen is not divisible by cipher block size.
