Metadata.Hash Property ActiveX/Java Uploader PHP
Gets or sets an algorithm to generate a hash value for each user-selected file.
Syntax
public function getHash() {
}
public function setHash($value) {
}Property Value
Type: string
The algorithm to generate a hash value for each user-selected file.
Possible values are listed in the table below.
| Value | Description |
|---|---|
| SHA | SHA hash algorithm. |
| MD2 | MD2 hash algorithm. |
| MD5 | MD5 hash algorithm. |
You can specify several hash algorithms separated by semicolon.
Default value is "".
Remarks
ActiveX/Java Uploader Express does not upload hash sums. See the Upload Suite Editions topic for details.
The hash is calculated only for the original file, not for converted files (even if the original file is not uploaded).
To get an uploaded hash sum at the server, use the Package.PackageFields collection.
Here this value can be retrieved by a key named in the following way: HashCodeXXX_N, where XXX is a string value specified in this property (hash algorithm),
and N is the index of the file in the request. E.g. if the property value is MD5;SHA, the PackageFields
collection will contain the following keys:
HashCodeMD5_1,HashCodeMD5_2, etc.HashCodeSHA_1,HashCodeSHA_2, etc.
Hash calculation is quite resource-intensive operation. That is why if you do not need to verify uploaded files on the server, it makes sense to disable this feature to make ActiveX/Java Uploader faster. To do it, just specify empty string in this property.
