The Erlang port of Hashids from JavaScript.
Add Hashids as a dependency to rebar.config
{deps,
[
{hashids, ".*", {git, "git://github.com/snaiper80/hashids-erlang.git", {tag, "1.0.2"}}}
]
}.Hashids encodes a integer or a list of integers.
1> hashids:new(). % create a new hashids context with default options
{hashids_context,"this is my salt",8,
"5N6y2rljDQak4xgzn8ZR1oKYLmJpEbVq3OBv9WwXPMe7",
"UHuhtcITCsFifS","AdG0"}
2> hashids:new([]). % same as new/0
{hashids_context,"this is my salt",8,
"5N6y2rljDQak4xgzn8ZR1oKYLmJpEbVq3OBv9WwXPMe7",
"UHuhtcITCsFifS","AdG0"}
3> Ctx = hashids:new([{salt, "this is my salt"}, {min_hash_length, 8}]).
{hashids_context,"this is my salt",8,
"5N6y2rljDQak4xgzn8ZR1oKYLmJpEbVq3OBv9WwXPMe7",
"UHuhtcITCsFifS","AdG0"}
4> Encoded = hashids:encode(Ctx, 12345).
"B0NkK9A5"
5> Encoded2 = hashids:encode(Ctx, [12345, 6789]).
"Y9awcOLv"decode/2 returns a list of numbers
6> hashids:decode(Ctx, Encoded).
[12345]
7> hashids:decode(Ctx, Encoded2).
[12345,6789]You can use customized characters (least 16 characters long)
