B4X

Calculate MD5 Hash of File (or SHA1, SHA256, and other hash algorithms)

See more Encryption Examples

Demonstrates how to calculate a hash for a file's contents. B4X

'  This example assumes the Chilkat API to have been previously unlocked.
'  See Global Unlock Sample for sample code.

Dim crypt As ChilkatCrypt2
crypt.Initialize("crypt")

'  Set the name of the hash algorithm.
'  Other choices include "sha1", "sha256", "sha384", "sha512", "md2", "md5", and "haval". 
crypt.HashAlgorithm = "md5"

'  EncodingMode specifies the encoding of the hash output.
'  It may be "hex", "url", "base64", or "quoted-printable".
crypt.EncodingMode = "hex"

'  Files of any type may be hashed -- it doesn't matter
'  if the file is binary or text...
Dim hashStr As String
hashStr = crypt.HashFileENC("/temp/something.dat")
If crypt.LastMethodSuccess <> True Then
    Log(crypt.LastErrorText)
    Return
