K9Crypt

K9Crypt is a user-friendly and modern encrypted messaging platform focused on data security. It allows users to create and share secure and confidential messages without the need to create an account. It provides the highest level of data protection with five layers of encryption (AES-GCM, AES-CBC, AES-CFB, AES-OFB and AES-CTR) and integrity verification with HMAC. In addition, your data is compressed with the Brotli compression algorithm before encryption, reducing data size and speeding up transfer processes. There are no limits on messages and chat rooms, and all content is automatically deleted after 4 hours for security purposes. K9Crypt is developing as an open source project with community support and aims to increase sustainability and security with a semi-open source model. Offering a modern, fast and easy-to-use interface for users, K9Crypt is the ideal platform for those looking for a powerful solution for privacy and data security.
