CryptoDataUtility

The CryptoDataUtility allows the user to decrypt a string without specifying the keyName. To accomplish this, the cipher text, at the time of encryption, is bundled with the same meta data, of the key, which was used for encryption.

On installing CADP for C:

• For Linux, the libCryptoDataUtility.so gets installed in the "CADP_for_C" directory.

• For Windows, the CryptoDataUtility.dll gets installed in the "C:\Program Files\CipherTrust\CADP_for_C" directory.

The user must explicitly add reference of libCryptoDataUtility.so to the application.

Supported Platforms

The CryptoDataUtility is supported on the following platforms:

• Windows Server

Supported Algorithms

Currently, this utility supports only AES algorithm.

Supported APIs

Encrypt

• keyName: name of the key

• inData: input data to encrypt

• datalen: length of inData

• outdata: Address of unallocated buffer, please set *outdata = NULL before passing it

• sess : An CAPI open session

• Return: length of outdata and 0 in case of error

  int Encrypt(char* keyName ,unsigned char* inData, unsigned int datalen, unsigned char**outdata ,I_O_Session sess) ;

  

  Note

  Encrypt returns the bundled cipher text (i.e. cipher text with key metadata)

Decrypt

• inData: input data, this is the value filled in outdata parameter of Encrypt() API

• length: Length of inData, returned by Encrypt()

• outputData: Address of unallocated buffer, please set *outputData = NULL before sending it.

• sess: An CAPI open session

• freeIndata: set to 0 - user will free inData, set to 1 - Decrypt() will free it

• Return: length of outputData and 0 in case of error
