What is 128-Bit Encryption? - Definition from Techopedia

How long would it take to bruteforce an AES-128 protected A-Z and 0-9 means 36 possible characters. 20 such characters imply 36 20 possible keys. That's approximately equal to 2 103.4.. The biggest brute force effort currently known publicly was for a 64-bit key (for RC5, but the difference between RC5 and AES is not important here); it is described here.It took almost five years and a lot of contributors; the peak cracking rate was equivalent to What’s the deal with encryption strength —is 128 bit May 06, 2016

Cracking Encryption: Despite Benefits, Technology Still

Jul 07, 2016 · Passwords and the encryption standard (128 bit in this case) have nothing to do with each other. The encryption is done exactly the same way whether you have a 3 character password or a 300 character password. Hacking an encryption means bypassing the password completely. Each bit represents a specific setting regarding that user account. For example, when an account is disabled the second low-order bit is set to “1”. In the case of reversible encryption, it is the 8th low-order bit that would be set to “1”. The 8th low-order bit corresponds to the decimal value 128. (I told you we were getting into the

You use 128-bit and 256-bit keys with symmetric-key encryption (e.g., AES). Quantum computers are useless there, as they give you no benefit over classical computers. For integer factorization based keys, where quantum computers would be useful in cracking keys, nobody would ever use keys as short as 256 bits. 2048 bits would be more typical.
