hashing encoded arrays?

[makeshyft]

Hi there.

lets say I encode an array full of data and then get a hash of it ..... given the identical set of keys and data...am i guaranteed the same hash on every platform? or is ordering something I need to consider? ... I MUST guarantee the same hash........or is this a bad idea?

Thanks

Assuming you're using LC's built-in hash functions, the hash should be the same on the same data. But as far as creating that data from an array, I wouldn't count on the serialized form of an array remaining the same across platforms or possibly even across sessions on the same platform.

yeah...... that was my worry.

hmmmm.. not sure what to do to solve this. Thanks Richard

An array only lives in the current session anyway. Maybe you could create the hash from the data used to populate the array, or save the serialized form?

that seems like the only option ... thanks for your help.
