Decrypted RSA 64 bit encryption using modulus and private exponent. Got gobbledygook [Verify]
I did the procedure myself, and I can confirm that base64 decoding will do the trick; the full decrypted file will have == at the end somewhere. After decoding, the "file" command will reveal the plain text type. The '.uyu' file is quite easy to "decrypt" as well, I noted.
