Creates a SHA-256 message digest in hexadecimal format
from a message of String type.
Public Declare Function SHA2_StringHexHash Lib "diCryptoSys.dll"
(ByVal strDigest As String, ByVal strMessage As String) As Long
nRet = SHA2_StringHexHash(strDigest, strMessage)
long __stdcall SHA2_StringHexHash(char *szDigest, const char *szMessage);
If successful, the return value is 0; otherwise it returns a non-zero error code.
Sha256.HexHash Method (String)
sha256.StringHexHash
Public Function StringHexHash(ByVal strData As String) As String
See sha256.StringHexHash.
szDigest must be at least 64 (API_MAX_SHA2_CHARS) characters long (65 in a C program).
Dim nRet As Long
Dim strDigest As String
' Set strDigest to be 64 chars
strDigest = String(64, " ")
nRet = SHA2_StringHexHash(strDigest, "abc")
Debug.Print strDigest
nRet = SHA2_StringHexHash(strDigest, _
"abcdbcdecdefdefgefghfghighijhijkijkljklmklmnlmnomnopnopq")
Debug.Print strDigest
This should result in output as follows:
