256-bit encryption is a data/file encryption technique that uses a 256-bit key to encrypt and decrypt data or files. It is one of the most secure encryption methods after 128- and 192-bit encryption, and is used in most modern encryption algorithms, protocols and technologies including AES and SSL.
Bitwarden uses AES 256 bit encryption as well as PBKDF2 to secure your data. AES is a standard in cryptography and used by the US government and other government agencies around the world for protecting top secret data. With proper implementation and a strong encryption key (your master password), AES is considered unbreakable. 256 Bit Encryption: Is AES-256 Bit Encryption Safe in So that was our explanation of how secure is 256-bit AES encryption. The bottom line is that it’s the most secure encryption method that you can use today, and it’ll remain so in the foreseeable future. You can start using it for the security of sensitive data in your enterprise. How safe is a AES 256 Bit Encryption? | VComply
How Safe is Bank-Level Encryption? - Alarm New England Jul 09, 2019 cryptography - Why most people use 256 bit encryption The answer is that it is never secure enough (even though I suspect that using 256 bit vs 128 bit keys is a marketing strategy to make the client feel more secure). And don't forget the rise of quantum computing, which significantly lowers the amount of time needed for a brute-force attack.
To protect your content in transit, Airtable uses 256-bit SSL/TLS encryption. At rest, Airtable content is protected using 256-bit AES encryption. Airtable's production data is regularly backed up to a separate, isolated location and all backups are encrypted.
This is where the Advanced Encryption Standard (AES) comes in. Originally adopted by the federal government, AES encryption has become the industry standard for data security. AES comes in 128-bit, 192-bit, and 256-bit implementations, with AES 256 being the most secure. How Safe is AES Encryption? | Advanced Encryption Standard
