17 sie 2010 · I would like to convert a number of excel cells in my document from a serial number to the MD5 hash of that serial number. Is there a precompiled formula in excel that does that, or is my only option to do VBA. If VBA, how would I do it?
For a reasonably small list you can create a scrambler (poor man's hash function) using built-in Excel functions. E.g. =CODE(A2)*LEN(A2) + CODE(MID(A2,$A$1,$B$1))*LEN(MID(A2,$A$1,$B$1))
30 mar 2014 · Say you want the MD5 or SHA1 of a Single Sheet of the cells A2, B4, B5, C3, C6 and D7 as well as E9, the following formula will populate the cell it is on with the md5. The Formula is for MD5 (insecure): =WEBSERVICE (CONCATENATE ("http://hashing.labs.coop/v1/md5/raw.api?data=",A2, B4, B5, C3, C6, D7, E9)) The Formula is for SHA1 (insecure):
Public Function MD5Hex(textString As String) As String Dim enc Dim textBytes() As Byte Dim bytes Dim outstr As String Set encoder = CreateObject("System.Text.UTF8Encoding") Set enc = CreateObject("System.Security.Cryptography.MD5CryptoServiceProvider") textBytes = encoder.GetBytes_4(textString) bytes = enc.ComputeHash_2((textBytes)) For pos = 1 ...
Using the MD5 hashing algorithm, the function helps encode any text string into a 128-bit hash value. Supported encodings include: ASCII, Unicode, BigEndianUnicode, UTF7, UTF8, UTF32. Functions are one of the 20+ features within XLTools Add-in for Excel. Works in Excel 2019, 2016, 2013, 2010, desktop Office 365.
5 sie 2015 · Hi, here's the code in text: Debug.Print FileToMD5Hex("C:\test.txt") Dim enc. Dim bytes. Dim outstr As String. Dim pos As Integer. Set enc = CreateObject("System.Security.Cryptography.MD5CryptoServiceProvider") 'Convert the string to a byte array and hash it. bytes = GetFileBytes(sFileName) bytes = enc.ComputeHash_2((bytes))
HashAlgorithm = "md5" hash = crypt. HashStringENC (s) Debug.Print "MD5: " ; hash ' Note: SHA-2 is a set of cryptographic hash functions (SHA-224, SHA-256, SHA-384, SHA-512) ' Hash using SHA-256 crypt.
