Otherwise, a third party can potentially eavesdrop on the communication and intercept public key requests, substituting its own public key for a legitimate key (the man-in-the-middle attack). In order to establish secure communications, it is important to verify that the public key used to encrypt a message does in fact belong to the target recipient. Public-key algorithms can guarantee the secrecy of a message, but they don't necessarily guarantee secure communications because they don't verify the identities of the communicating parties. The private key is securely stored, together with other security credentials, in an encrypted container-called a wallet. The freely available public key is used to encrypt messages that can only be decrypted by the holder of the associated private key. Public-key cryptography provides a solution to this problem, by employing public/private key pairs and a secure method for key distribution. The problem with this method is that it is difficult to securely transmit and store the key. ![]() This key is used to both encrypt and decrypt secure messages sent between the parties, requiring prior, secure distribution of the key to each party. Traditional private-key or symmetric-key cryptography requires a single, secret key that is shared by two or more parties to a secure communication.
