What is the "wallet export format"? The "wallet export format" is mentioned at the Wiki page for Mini private key format, but it doesn't seem to be explained on the Wiki. How does one convert the export format to and from corresponding keys?
As it was explained on the forum, it is a base58 encoded private key with added 0x80 byte at the front and 4 checksum bytes at the end.

More detailed explanation is not available on the wiki, as well as in a new testing suite.
