Platforms:

All

Parameters:

data - required

String to be hashed.

algorithm - required

Specify the type of hashing algorithm to use to create the hash value. Can have one of the following values:

"SHA-512"

"SHA-256"

"SHA1"

"MD5"

"MD4"

The values above are listed in order of decreasing security.

encoding - required

Specify the Unicode format in which the string in the data parameter above is formatted:

"UTF-16" - The input string is formatted using Unicode UTF-16 format, e.g. SQL Server nchar or nvarchar data type.

"UTF-8" - The input string is formatted using Unicode UTF-8 format, e.g. SQL Server char or varchar data type.

Returns:

String containing the hash value generated from the input string.

Notes:

If you are specifying UTF-8 encoding, make sure your supplied value doesn't include UTF-16 characters, such as £ or € symbols, otherwise if you attempt to compare the hash value returned by this Method with a hashed value obtained from elsewhere the hashes might not match.
