fgl_hash()

fgl_hash() converts the character string specified as its 2nd parameter into the hash type specified as the 1st one.

Syntax

CALL fgl_hash(hash_type, string)

Parameters

hash_type

the type of the hash to be used for converting string

(can be a string of characters or a variable of the STRING data type)

string

the string to be converted into the specified type of hash

(can be a string of characters or a variable of the STRING data type)

Usage and examples

Simple programs given below show how the function can be used and what results it provides:

example code #1	MAIN DEFINEstrHashSTRING LETstrHash = fgl_hash("crc32", "1234567") DISPLAYstrHash CALLfgl_getkey() END MAIN
example code #2	MAIN DEFINEstrHash, strValue, strHashAlgorithmNameSTRING LETstrValue = "1234567" LETstrHashAlgorithmName = "crc32" LETstrHash = fgl_hash(strHashAlgorithmName, strValue) DISPLAYstrHash CALLfgl_getkey() END MAIN
obtained results #1-2
example code #3	MAIN DEFINE strHash, strValue, strHashAlgorithmName STRING DEFINE arrAllSupportedHashAlgorithmNames DYNAMIC ARRAY OF STRING DEFINE i INT LET arrAllSupportedHashAlgorithmNames = fgl_get_supported_hash_algorithms() DISPLAY "supported hash algorithms are: ", arrAllSupportedHashAlgorithmNames LET strValue = "12345" DISPLAY "value: ", strValue FOR i = 1 TO arrAllSupportedHashAlgorithmNames.getLength() LET strHashAlgorithmName = arrAllSupportedHashAlgorithmNames[ i] LET strHash = fgl_hash(strHashAlgorithmName, strValue) DISPLAY strHashAlgorithmName, ": ", strHash END FOR CALL fgl_getkey() END MAIN
obtained results #3
