Text Encryptor: Protect your messages, notes, cryptocurrency keys (seeds, mnemonics), and other sensitive text from unauthorized access. Use the internal database or simply copy and paste to/from your favorite apps. Set a password for each encryption/decryption session — you can use an unlimited number of passwords for different purposes (e.g., notes, emails, social networking, or communication with individuals A, B, C, etc.).
