sha256 encryption code example

Example 1: swift sha256 encryption

extension String {

    func sha256() -> String{
        if let stringData = self.data(using: String.Encoding.utf8) {
            return hexStringFromData(input: digest(input: stringData as NSData))
        }
        return ""
    }

    private func digest(input : NSData) -> NSData {
        let digestLength = Int(CC_SHA256_DIGEST_LENGTH)
        var hash = [UInt8](repeating: 0, count: digestLength)
        CC_SHA256(input.bytes, UInt32(input.length), &hash)
        return NSData(bytes: hash, length: digestLength)
    }

    private  func hexStringFromData(input: NSData) -> String {
        var bytes = [UInt8](repeating: 0, count: input.length)
        input.getBytes(&bytes, length: input.length)

        var hexString = ""
        for byte in bytes {
            hexString += String(format:"%02x", UInt8(byte))
        }

        return hexString
    }

}

Example 2: keytool command sha256

keytool -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

Example 3: sha256_crypt.verify

from passlib.hash import sha256_crypt

password = sha256_crypt.encrypt("password")
password2 = sha256_crypt.encrypt("password")

print(password)
print(password2)

print(sha256_crypt.verify("password", password))

Example 4: sha256_crypt.verify

import hashlib

user_entered_password = 'pa$$w0rd'
salt = "5gz"
db_password = user_entered_password+salt
h = hashlib.md5(db_password.encode())
print(h.hexdigest())

Example 5: sha256_crypt.verify

import hashlib
password = 'pa$$w0rd'
h = hashlib.md5(password.encode())
print(h.hexdigest())
