## Discussion

Discussion important: This type is deprecated. Use internet password items instead of AppleShare password items. This type represents a 16-byte Apple File Protocol server signature block. You can use a value of this type with the keychain item attribute constant SecItemAttr.signatureItemAttr to specify an Apple File Protocol server signature.
