I do know that SHA-256 produces 64 characters of hashed string regardless of what the input is.Not only is SHA-256 not an encryption algorithm, it is a cryptographic hash function, so my question was a.SHA-256 (256 bit) is part of SHA-2 set of cryptographic hash functions, designed by the U.S. National Security Agency (NSA) and published in 2001 by the NIST as.
Won't ASIC miners eventually break SHA-256 encryption?

RC2, RC4, 128-bit RC4, DESX, 128-bit AES, 192-bit AES, and 256-bit AES.But, those 64 characters have a maximum entropy of 256 bits or 32 bytes.A common use for SHA-256 is for password encryption as it is one-way in nature, that does not mean that your passwords are not free from a dictionary attack.
You should not just send it through SHA-256 or put it directly into the key.Google is encouraging businesses and security practitioners to utilize cryptographic hashes like SHA.
SHA1 algorithm securing e-commerce and software couldNow, stepping back a little, the best advice I can give you is to not roll your own crypto protocol and instead use a widely accepted standard.
