I have this random 'd9b3b2d69bab862a' values when i do encoding. But i can not decode it back to abcd. Any idea how to do it?

If you want to use bin2hex to 'encode' the binary data so it is easily transported over http/url, here is what you can do to reverse it back to binary:

Other minor issues with your class was the references to $key and $vector.Since both methods are static, they cannot access $this and $key and $vector alone are undefined.

The following code should work for you:

Alternatively, you could use base64_encode in your getEnc function, and base64_decode in the getDec function. Base64 is commonly used to represent binary data from encryption.

3.0.0 - 2016-06-21

Added

  • #22 adds a requirementon ext/mbstring in order to install successfully.
  • #25 adds a newsymmetric encryption adapter for the OpenSSL extension; this is now thedefault adapter used internally by the component when symmetric encryption isrequired.
  • #25 adds support forzend-math v3.
  • #26 addsZendCryptPasswordBcrypt::benchmarkCost(), which allows you to find themaximum cost value possible for your hardware within a 50ms timeframe.
  • #11 adds a new optionto the ZendCryptPublicKeyRsaOptions class, openssl_padding (orsetOpensslPadding(); this is now consumed inZendCryptPublicKeyRsa::encrypt() andZendCryptPublicKeyRsa::decrypt(), instead of the optional $paddingargument.

Deprecated

  • #25 deprecates usage of themcrypt symmetric encryption adapter when used on PHP 7 versions, as PHP 7.1will deprecate the mcrypt extension.

Removed

  • #11 removes theoptional $padding argument from each of ZendCryptPublicKeyRsa'sencrypt() and decrypt() methods; you can now specify the value via theRsaOptions.
  • #25 removes support forzend-math v2 versions.
  • #29 removes support forPHP 5.5.

Fixed

  • #22 updates alloccurrences of substr() and strlen() to use mb_substr() andmb_strlen(), respectively. This provides better security with binary values.
  • #25 updates theZendCryptPasswordBcrypt implementation to use password_hash() andpassword_verify() internally, as they are supported in all PHP versions wesupport.
  • #19 fixes theDiffieHellman publickey implementation to initialize the BigIntegeradapter from zend-math as the first operation of its constructor, fixing afatal error that occurs when binary data is provided.

2.6.0 - 2016-02-03

Added

  • #18 adds documentation,and publishes it to https://zendframework.github.io/zend-crypt/

Deprecated

  • Nothing.

Removed

  • Removes the (development) dependency on zend-config; tests that used itpreviously have been updated to use ArrayObject, which implements the samebehavior being tested.

Fixed

  • #4 replacesthe zend-servicemanager with container-interop, and refactors thevarious plugin managers to implement that interface instead of extending theAbstractPluginManager.

2.5.2 - 2015-11-23

Added

  • Nothing.

Deprecated

  • Nothing.

Php Zend Framework

Removed

  • Nothing.

Fixed

  • ZF2015-10: ZendCryptPublicKeyRsaPublicKey has a call to openssl_public_encrypt()which used PHP's default $padding argument, which specifiesOPENSSL_PKCS1_PADDING, indicating usage of PKCS1v1.5 padding. This paddinghas a known vulnerability, theBleichenbacher's chosen-ciphertext attack,which can be used to recover an RSA private key. This release contains a patchthat changes the padding argument to use OPENSSL_PKCS1_OAEP_PADDING.

    Users upgrading to this version may have issues decrypting previously storedvalues, due to the change in padding. If this occurs, you can pass theconstant OPENSSL_PKCS1_PADDING to a new $padding argument inZendCryptPublicKeyRsa::encrypt() and decrypt() (though typically thisshould only apply to the latter):

    where $rsa is an instance of ZendCryptPublicKeyRsa.

    (The $key and $mode argument defaults are null andZendCryptPublicKeyRsa::MODE_AUTO, if you were not using them previously.)

    We recommend re-encrypting any such values using the new defaults.
