The Heartbleed Bug is a serious vulnerability in the OpenSSL cryptographic software that protects a majority of the world’s encrypted or “secure” sites. Encryption works by using “keys” (a number, or sequence of characters) to encode a sent message. The receiving computer uses the key to decrypt the message. If intercepted by a third party, the message should be unreadable.
