In case of RAR there is a CRC of the original file stored in the archive. Instead of looking for known plaintext, you do a CRC of the full decrypted and inflated file and see if it matches. For large files, this is very slow so you want early rejection. Early rejection can be made by decrypting just a block or two and analyzing the Huffman encoding. That is tricky sh!t, believe me.
