Why is it necessary to encrypt text?
Text encryption is a technique of converting text into an unreadable form that can only be decoded by someone who has the key or knows the method. Practical application: Information security - encrypt passwords, API keys, sensitive information before storing or transmitting. Secure data transmission - send information over non-secure channels (email, chat). Privacy - hides content from unauthorized users. Learn cryptography - understand basic and advanced encryption algorithms. Fun & games - create secret messages with friends, puzzles, escape rooms. Development - test encryption/decryption in the application.
