Java sha-256 encryption decryption example

Can we decrypt sha256

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.

Java sha256 hex digest

import org.apache.commons.codec.digest.DigestUtils;

String password = "123456";
String result = DigestUtils.sha256Hex(password);

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());
