Encryption details. All messages that are transferred using Unseen are encrypted and decrypted by users of the service, not by Unseen. According to the FAQ page of the service, it does not have access to the key. Messages are encrypted using 4096-bit encryption and "advanced symmetrical encryption".

Jan 01, 2016 · For 4096 bit key encryption, the time may exceed the shelf life of the Milky Way Galaxy. But there are side channel attacks that one can perform. This means there are ways to exploit the vulnerabilities that exist in the implementation of the RSA encryption/decryption algorithm in a device. This includes measuring variations in CPU voltage, noise produced by a device during encryption/decryption of a RSA encrypted message (the messages are generally AES keys). Dec 19, 2013 · Credit: Daniel Genkin et al. (Phys.org) —A trio of researchers in Israel has discovered that it is possible to crack 4096-bit RSA encryption keys using a microphone to listen to high-pitch To protect a 256-bit symmetric key (e.g. AES-256), you may consider using at the minimum a 17120-bit asymmetric system (e.g. RSA). The 4096 bit limit can be raised as described in a short article entitled "Generate large keys with GnuPG", reproduced below. This was done for the gnupg package in homebrew to allow for 8192 bit keys: PR 4201.
The selected strong WAS cipher suite together with a RSA key size of 4096-bit require a lot more CPU resources for the cryptographic operations. If the 4096-bit cryptographic operations are calculated completely in software, the available CPU resources are fully used quickly.
Researchers Break RSA 4096 Encryption With Just A Dec 21, 2013 Products - Encryption Software, Cryptography Software Software for RSA 2048 bit Encryption/Decryption using a 2048 bit public key. Download RSA 2048 bit Cryptography or cryptographic software here. Password protected RSA keys. Meant for limited encryption of Plain text. You also get priviledges to send encrypted mail to multiple reciepients. RSA2048 CryptoSystem - Encryption Software, Cryptography RSA 2048 bit crytographic software download. Used for limited ammount of Text, as the keys are quazi keys - often not real and will not do for bulk encryption. It uses Java's BigInteger class which is efficient at generating large primes, and the algorithms are extremely fast, allowing good response times.
