问题 I am trying to recreate some openssl php code in the command-line. I have been able to get the following php code to work: $key = 'aaaaaaaabbbbbbbbccccccccdddddddd'; $key = pack('H*',$key); $data = 'b5057bbc04b842a96144a0f617f2820e'; $data = pack('H*',$data); $result = openssl_decrypt($data,'des-ede', $key, OPENSSL_RAW_DATA | OPENSSL_ZERO_PADDING); The Command I'm Working on (Ubuntu) openssl des-ede -in encrypted-data.txt -out decrypted-data.txt -d -K aaaaaaaabbbbbbbbccccccccdddddddd -nopad

问题 I've already looked through answers to other questions on the Sagepay protocol upgrade from 2.22 to 3.00, including the answer on my own previous question. I am trying to update the encryption method from Xor to AES so the 3.00 protocol will work but have thus far got stuck on the Sagepay error 5068: the encryption method is not supported by this protocol. My company's three websites that need to be updated are based on the JShop e-commerce platform which is very outdated and no longer offers

问题 when i take a look at the paypal documentation, they say "Note that the PayPal SDK for PHP does not require SSL encryption". https://developer.paypal.com/docs/classic/api/apiCredentials/#encrypting-your-certificate Is the statement of this phrase, that i don't have to create a p12 certificate when working with php, but use the public_key.pem and paypal_public_key.pem ? If yes: Is it secure enough to create the encrypted form input elements without p12 certificate? If no: What do they mean? :-

问题 Folks, I need to encrypt some string data into a SQL database from and MVC Core 2.0 application. I'm thinking of using the Data Protection API with PersistKeysToFileSystem so that I can restore the data to another server and decrypt the data using the same key file. I am impressed with the performance of the DPAPI in Net core and I don't want to fo for any custom crypto solution as its too risky. I would be storing bulk uploads of data to SQL. Strings before encryption would be 200 chars or

问题 In ColdFusion, What is the best best of doing a user login password comparison with the database that will encrypt the password between the client and server? I noticed there's a javascript version at http://pajhome.org.uk/crypt/md5/index.html but what can be done for users without javascript enabled? 回答1: These points are not specific to coldfusion, but I feel I must state them: Do the hash server-side. The point of hashing is to make it really hard to figure out what to send the server in

问题 I was designing a system where there is a chance of losing the SSL certificate to the attacker. But I am not clear that if the certificate is compromised which all attacks are possible? Man in the middle attack Impersonated attack I want to continue to use SSL certificates to encrypt the communication channel (i.e. prevent man in the middle attack) For authentication I want to send data to predefined end points asynchronously depending on the querying user (Very similar to how we get email

问题 I'm porting some code from PHP to .NET (I'm not a PHP developer) and it all looks pretty straightforward apart from the following line: public function hash($message, $secret) { return base64_encode(hash_hmac('sha1', $message, $secret)); } How can I port this function to .NET? The base64 encoding is done as follows, but how do I replicate hash_hmac()? Convert.ToBase64String(System.Text.Encoding.ASCII.GetBytes(tmpString)); Thanks! 回答1: If you're looking for an HMAC then you should be using a

问题 I want to create AES encryption and decryption program in symbian which must be compatible with AES encryption in java Means if I encrypt the data in Symbian I must be able to decrypt the same in java and vice versa Thanks Sunil 回答1: They have a implementation of AES (encrypt and decrypt) as part of their main crypto library. Look for CAESEncryptor and CAESDecryptor. If the Java and Symbian aren't compatible, there's a bug in one. Good luck finding which. ;) 来源： https://stackoverflow.com

问题 I am attempting to enable TLS 1.2 on our Windows 2008 R2 server for PCI compliance, and have managed to get it working by following this obscure blog post which requires turning on FIPS validation. Finally, after weeks of looking for a solution, click-once, .NET remoting, and MS Web Deploy are communicating over TLS 1.2. However, I also have web applications on the machine that quit functioning when I enabled FIPS validation with the following error: This implementation is not part of the
