' 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
sha256_hex = sb.GetHash("sha256","hex","utf-8")
Response.Write "<pre>" & Server.HTMLEncode( "SHA256: " & sha256_hex) & "</pre>"

' Get the SHA384 hash in hex lowercase
sha384_hex = sb.GetHash("sha384","hex_lower","utf-8")
Response.Write "<pre>" & Server.HTMLEncode( "SHA384: " & sha384_hex) & "</pre>"

' Get the SHA512 hash in base64
sha512_base64 = sb.GetHash("sha512","base64","utf-8")
Response.Write "<pre>" & Server.HTMLEncode( "SHA512: " & sha512_base64) & "</pre>"

' Get the SHA1 hash in hex lowercase
sha1_hex = sb.GetHash("sha1","hex_lower","utf-8")
Response.Write "<pre>" & Server.HTMLEncode( "SHA1: " & sha1_hex) & "</pre>"

' Get the CRC8 digest in decimal
crc8_decimal = sb.GetHash("crc8","decimal","utf-8")
Response.Write "<pre>" & Server.HTMLEncode( "CRC8: " & crc8_decimal) & "</pre>"
