oe

Implementation of the Progress OpenEdge ENCODE algorithm based on the CSharp and JAVA implementations as found in the pvginkel/ProgressEncode repository on GitHub.

Install

go get -u lab.madbox.synology.me/gophers/oe

Examples

// Either use the helper function Sum():
a := oe.Sum([]byte("admin"))
fmt.Println(string(a[:]))
// Output: aaLldOCddklvMUWh

// Or use a distinct hash.Hasher (useful when creating multiple hashes):
hasher := oe.New()
_, err := hasher.Write([]byte("admin"))
if err != nil {
  // ...
}
b := hasher.Sum(nil)
fmt.Println(string(b))
// Output: aaLldOCddklvMUWh

// Before reusing hasher, call Reset(), else it keeps appending.
hasher.Reset()

Overview

Package oe implements the Progress OpenEdge encode algorithm.

Index

• Constants
• func New() hash.Hash
• func OEcheck(input string) bool
• func Sum(data []byte) [Size]byte

Examples

• Sum

Constants

const BlockSize = 16

BlockSize is the blocksize of OEencode in bytes.

const Size = 16

Size is the size of an OEencode checksum in bytes.

Functions

func New

func New() hash.Hash

New returns a new hash.Hash computing OEencode checksums.

func OEcheck

func OEcheck(input string) bool

OEcheck does a simple verification of the input stream.

func Sum

func Sum(data []byte) [Size]byte

Sum returns the OEencode checksum of given byte array.

Example

h := Sum([]byte("admin"))
fmt.Println(string(h[:]))

Output:

aaLldOCddklvMUWh
