RC4 Encryption and decryption Tool

RC4 Encryption and decryption ToolIntroduction

1. rc4 (rivest cipher 4) is a stream cipher that is used to protect various forms of communication, especially in wireless communication and ssl/tls protocols.

2. rc4 has the advantages of fast speed, simple algorithm, variable key length, etc.

3. rc4 has weak keys, key stream deviations and security issues in which multiple key streams are restored to plaintext.

4. note: rc4 has been deprecated by many modern standards and protocols.
