Hash (Digest) a String

Hash the bytes of a string. B4X

Dim sb As ChilkatStringBuilder
sb.Initialize

sb.Append("Hello World")

'  Hashing algorithms (i.e. digest algorithms) operate on raw bytes.
'  Therefore, we must specify the character encoding (utf-8, utf-16, iso-8859-1, etc.) to be used when hashing.


'  Get the SHA256 hash in hex
Dim sha256_hex As String = sb.GetHash("sha256", "hex", "utf-8")
Log("SHA256: " & sha256_hex)

'  Get the SHA384 hash in hex lowercase
Dim sha384_hex As String = sb.GetHash("sha384", "hex_lower", "utf-8")
Log("SHA384: " & sha384_hex)

'  Get the SHA512 hash in base64
Dim sha512_base64 As String = sb.GetHash("sha512", "base64", "utf-8")
Log("SHA512: " & sha512_base64)

'  Get the SHA1 hash in hex lowercase
Dim sha1_hex As String = sb.GetHash("sha1", "hex_lower", "utf-8")
Log("SHA1: " & sha1_hex)

'  Get the CRC8 digest in decimal
Dim crc8_decimal As String = sb.GetHash("crc8", "decimal", "utf-8")
Log("CRC8: " & crc8_decimal)
