Example _php PHP docking Java reality plus sign verification

My implementation of the method, mainly to the Java generated key to PHP can recognize the key in PEM format, the other add-sign, check the use of call OpenSSL built-in signature method.

The key generated by Java is primarily a string, whereas the PEM format key is a 64-bit line with the following header and footer file formats, and PHP then obtains the relative PEM format string.

PEM format key

-----Begin public Key-----//64chars row (multiline)-----END public Key----------BEGIN RSA PRIVATE Key-----//64chars Row (multiline)----- END RSA PRIVATE KEY-----

1.java key to PEM-formatted PHP code

/** * Format the string format Public private key as a PEM format public key * @param $secret _key * @param $type * @return string */public static function Format_secret_ke Y ($secret _key, $type) {  //64 English characters followed by line feed "\ n", followed by line break "\ n"  $key = (WordWrap ($secret _key, (+), "\ n", true). " \ n ";  Add PEM format Header and tail  if ($type = = ' pub ') {    $pem _key = "-----BEGIN public key-----\ n". $key. "-----END public KEY-----\ n";  } else if ($type = = ' pri ') {    $pem _key = "-----BEGIN RSA PRIVATE key-----\ n". $key. "-----END RSA PRIVATE KEY-----\ n";  } else{    Echo (' Public private key type illegal ');    Exit ();  }  return $PEM _key;}

2. Add Sign

/** * RSA plus * @param $paramStr * @param $priKey * @return string */public static function sign ($PARAMSTR, $priKey) {  $s IGN = ";  Convert the string format Public private key to PEM format Public private key  $priKeyPem = Signutil::format_secret_key ($priKey, ' pri ');  Convert to OpenSSL key, must be a private key without pkcs8 conversion  $res = Openssl_get_privatekey ($priKeyPem);  Call OpenSSL built-in signature method, generate signature $sign  openssl_sign ($paramStr, $sign, $res);  Release Resource  Openssl_free_key ($res);  Base64 encoded signature  $signBase = Base64_encode ($sign);  URL encoded signature  $sign = UrlEncode ($signBase);  return $sign;}

3. Verification

/** * RSA Verification * @param $PARAMSTR * @param $sign * @param $pubKey * @return bool */public static function Verify ($PARAMSTR, $ Sign, $pubKey) {  //Convert string format Public private key to PEM format Public private key  $pubKeyPem = Signutil::format_secret_key ($pubKey, ' Pub ');  The conversion to the OpenSSL key must be a public key that is not pkcs8 converted  $res = Openssl_get_publickey ($pubKeyPem);  URL decoding signature  $signUrl = UrlDecode ($sign);  Base64 decoding signature  $signBase = Base64_decode ($SIGNURL);  Call OpenSSL built-in method verification, return bool value  $result = (bool) openssl_verify ($PARAMSTR, $signBase, $res);  Release Resource  Openssl_free_key ($res);  Returns whether the resource was successfully returned  $result;}

Above this PHP docking Java Reality plus sign verification of the example is small part of the whole content to share to everyone, I hope to give you a reference, but also hope that we support the script home.
