SHA256 is a hashing function, not an encryption function. Secondly, since SHA256 is not an encryption function, it cannot be decrypted. ... In that case, SHA256 cannot be reversed because it's a one-way function.sha256 decrypt
A hash function cannot be 'decrypted', but a rainbowtable
can be used to try and find a plaintext match. Still,
that doesn't guarentee a match.java sha256 hex digest
String password = "123456";
MessageDigest md = MessageDigest.getInstance("SHA-256");
byte[]hashInBytes = md.digest(password.getBytes(StandardCharsets.UTF__8));
//bytes to hex
StringBuilder sb = new StringBuilder();
for (byte b : hashInBytes) {
sb.append(String.format("%02x", b));
}
System.out.println(sb.toString());Copyright © 2021 Codeinu
