26 byte private key?

26 byte private key?

I've noticed websites like bitaddress.org generating private keys consisting of 26 bytes string (instead of 32).

For example, I received the following pair: Private: L1d2VhSoT6yBzvDqjnFC85zF23MFf4wZAVVJMeG6JongbL2UxEhS, Public: 1MNgBN9QpG6yy2H9xb9JCuwCtjeppNwj4X. How did they generate the public address from the above private key? Following the regular procedure, this private key should be invalid.

Edit:

I figured now that it should be a compressed private key. When it comes to generating a public key from a private key, what's the difference in the procedure with a compressed and uncompressed private key? How is a compressed private key generated from a given 32 byte string?

For example, on this answer, how did he generate KwntMbt59tTsj8xqpqYqRRWufyjGunvhSyeMo3NTYpFYzZbXJ5Hp from 1111111111111111111111111111111111111111111111111111111111111111?
