Both Outlook and Thunderbird, just to name two off the top of my head, support plugins to encrypt and decrypt email.
Symantec this week announced two new data- encryption options, one that is file-based encryption for use with Dropbox, and the second that works as an extension to the Apple iOS mail client to encrypt and decrypt documents.
Modern encryption is achieved with algorithms that use a "key" to encrypt and decrypt messages by turning text or other data into digital gibberish and then by restoring it to its original form.
Passwords and messages posted after estimated 200,000 decrypted.
Its lead article is a defense of Alger Hiss' purported innocence--at least an assault on the charge that the man identified as "Ales" in a Venona decrypt is not Alger Hiss, but a man named Wilder Foote.
You'll need something that decrypts the signal.
Free Outlook Add-In automates sending encrypted messages and automatically decrypts them when received.

E is encryption with a block cipher (let Dk (c) = p denote decryption).
Statistics of Random Permutations and the Cryptanalysis Of Periodic Block Ciphers
Decrypt: It takes as input a receiver’s private key Sr and a ciphertext ε, using the public parameters (params, PP ub), outputs a message m or the invalid symbol ⊥.
Provable Secure Identity Based Generalized Signcryption Scheme
Let IDSG = (S etup, E xtract, S ign, V erif y ), IDEC = (S etup, E xtract, E ncryp t, Decrypt) and IDSC = (S etup, E xtract, S igncrypt, U nsigncrypt) respectively be an identity based signature scheme, encryption scheme and signcryption scheme.
Provable Secure Identity Based Generalized Signcryption Scheme
Extract queries on IDB , and he cannot ask Decrypt query on target ciphertext ε∗ .
Provable Secure Identity Based Generalized Signcryption Scheme
Firstly, in Phase 2 of Def. 5, the adversary is prohibited from making Decrypt query on the challenge ciphertext.
Provable Secure Identity Based Generalized Signcryption Scheme
But, he can transform the challenge ciphertext into some valid encryption ciphertext and make Decrypt query on the corresponding encryption ciphertext.
Provable Secure Identity Based Generalized Signcryption Scheme
Simulator: E ncrypt(IDB , m), Decrypt(IDB , ε) The challenger can get receiver IDB ’s public key and private key.
Provable Secure Identity Based Generalized Signcryption Scheme
For decryption, the receiver generates the same pseudo-random noise sequence, realizes the same bit-wise XOR operation between the received ciphertext and the pseudo-random noise sequence and recuperates the original message.
Linear solutions for cryptographic nonlinear sequence generators
Yet only the website can decrypt your message.
Can Random Coin Flips Speed Up a Computer?
When A returns a bit b′ , C hO outputs 1 if and only if both b = b′ and there was no decryption query DO (sk, c) after the challenge query.
Random Oracles in a Quantum World
Upon receiving a message, Bob will use his key k and a decryption algorithm D to try recover the original message, i.e., he will perform D(mc , k) (Step 3).
Quantum Communication Complexity of Quantum Authentication Protocols
Such protocols provide the conditions to the parties produce a shared random secret key known only to them, which can then be used to encrypt and decrypt messages .
Quantum Communication Complexity of Quantum Authentication Protocols
Since Bob knows K , he decrypts the received state, performs a measurement, and, therefore, recovers RA .
Quantum Communication Complexity of Quantum Authentication Protocols
Alice decrypts the state with K and performs an exclusive-OR (XOR) operation with the resulting state and RA .
