EP_CryptHashBuffer

EP_CryptHashBuffer calculates hash of the user defined buffer.

Parameters

• Hash - the type of the hash for calculation.
  
  

  Hash Type	Parameter = Value
  XOR32	HASH_XOR32 = 0
  MD2	HASH_MD2 = 1
  MD5	HASH_MD5 = 2
  RipeMD160	HASH_RipeMD160 = 3
  SH1	HASH_SH1 = 4
  SHA224	HASH_SHA224 = 5
  SHA256	HASH_SHA256 = 6
  SHA384	HASH_SHA384 = 7
  SHA512	HASH_SHA512 = 8

• Buffer - a pointer to the memory buffer for hash calculating.
• Size - the size of the memory buffer.
• Digest - a pointer to the buffer for storing the hash value.

Return Value

If the function succeeds, the return value is the size of hash (that is stored in Digest buffer) in bytes. If the function fails, the return value is 0.

Remark

The function fails in the following cases:

• the input buffer is not allocated;
• the input buffer is not readable;
• Digest buffer is not allocated;
• Digest buffer is write protected;
• the application is not protected.

Definition
