Example of the rsa encryption/Decryption class library-php & python

Create an object in the early stage and write a php rsa help class library. first look at the usage method $ keysRsaHelper: new_rsa_key. After the key is generated, record the key value. $ privkey $ keysprivkey is omitted here; $ pubkey $ keyspubkey; * $ privkey ----- BEGINPRIVATEKEY ----- MIICdwIBADANBgkqhkiG9w0BA

The source code of the class library is as follows:

Class RsaHelper {private static $ _ privkey = ''; private static $ _ pubkey =''; private static $ _ isbase64 = false; /*** initialize the key value * @ param string $ privkey private key * @ param string $ pubkey public key * @ param boolean $ isbase64 base64 encoded? * @ return null */public static function init ($ privkey, $ pubkey, $ isbase64 = false) {self ::$ _ privkey = $ privkey; self ::$ _ pubkey = $ pubkey; self :$ _ isbase64 = $ isbase64 ;} /*** private key encryption ** @ param string $ data original text * @ return string ciphertext */public static function priv_encode ($ data) {$ outval = ''; $ res = openssl_pkey_get_private (self: $ _ privkey); openssl_private_encrypt ($ data, $ outval, $ res); if (self: $ _ isbase64) {$ outval = base64_encode ($ outval);} return $ outval ;} /*** public Key decryption * @ param string $ data ciphertext * @ return string original text */public static function pub_decode ($ data) {$ outval = ''; if (self :: $ _ isbase64) {$ data = base64_decode ($ data);} $ res = openssl_pkey_get_public (self ::$ _ pubkey); openssl_public_decrypt ($ data, $ outval, $ res ); return $ outval;}/*** public key encryption * @ param string $ data original * @ return string ciphertext */public static function pub_encode ($ data) {$ outval = ''; $ res = openssl_pkey_get_public (self: $ _ pubkey); openssl_public_encrypt ($ data, $ outval, $ res); if (self: $ _ isbase64) {$ outval = base64_encode ($ outval);} return $ outval ;} /*** Private Key decryption * @ param string $ data ciphertext * @ return string original text */public static function priv_decode ($ data) {$ outval = ''; if (self:: $ _ isbase64) {$ data = base64_decode ($ data);} $ res = openssl_pkey_get_private (self ::$ _ privkey); openssl_private_decrypt ($ data, $ outval, $ res); return $ outval;}/*** create a set of public key private keys * @ return array public Key Private Key array */public static function new_rsa_key () {$ res = openssl_pkey_new (); openssl_pkey_export ($ res, $ privkey); $ d = openssl_pkey_get_details ($ res); $ pubkey = $ d ['key']; return array ('privkey' =>$ privkey, 'pubkey' =>$ pubkey );}}

Mom, the php protobuf under the win platform is tossing me and changing it to py. So, the python version of the rsa encryption helper class is coming.

def new_keys():    (bob_pub, bob_priv) = rsa.newkeys(1024)    return {'pubkey':bob_pub.save_pkcs1(), 'privkey':bob_priv.save_pkcs1()} class RsaHelper:     def __init__(self, privkey, pubkey):        self._privkey = privkey.decode('string-escape')        self._pubkey = pubkey.decode('string-escape')     def encode_priv(self, data):        privkey = rsa.PrivateKey.load_pkcs1(self._privkey)        crypto = rsa.encrypt(data, privkey)        return crypto     def decode_pub(self, data):        pubkey = rsa.PublicKey.load_pkcs1(self._pubkey)        msg = rsa.decrypt(data, pubkey)        return msg     def decode_priv(self, data):        privkey = rsa.PrivateKey.load_pkcs1(self._privkey)        msg = rsa.decrypt(data, privkey)        return msg     def encode_pub(self, data):        pubkey = rsa.PublicKey.load_pkcs1(self._pubkey)        crypto = rsa.encrypt(data, pubkey)        return crypto
