Gpg is a free tool which is used to encrypt a single file or folder with few commands, the only way to decrypt those files is with password. Note: a lower Entropy number means it is the most likely correct result. RC4 was initially a trade secret, but in September 1994 a description of it was anonymously posted to the Cypherpunks mailing list. WPA2 uses the Advanced Encryption Standard (AES) and Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP), respectively. Deciphering is reversing a cipher into the original text. Sha-2 algorithm was developed by NSA to answer the security problem of Sha-1, since the theorical discover of a 2^63 operations for collisions. Decrypting WEP frames is fairly simple, given the WEP key, it's just using RC4 over the encrypted data. RC4 – Symmetric Ciphers Online. While it is officially termed "Rivest Cipher 4", the RC acronym is alternatively understood to stand for "Ron's Code" (see also RC2, RC5 and RC6). It consists of a network packet analyzer, a WEP network cracker, and WPA / WPA2-PSK along with another set of wireless auditing tools. You always want to use a salt while encrypting. 05-22-2020, 11:06 PM .
