I need to use X509 certificate in the BizTalk Custom Pipeline component to Encrypt/Sign the message and to Decrypt/Verify signature, please let me know some good samples/artcile/blogs etc which explains how to acheive this.
RSA needs to be the encrypton algoritham.
Thanks.
What kind of encryption are you looking for? Are you looking for raw RSA encryption, or any specific message format?
Out of the box, BizTalk only supports S/MIME encryption using the SMIME encoder/decoder component; it might be useful depending on exactly your format is.
As for how to create a custom pipeline component from scratch to do it, I recommend first starting with the Pipeline Component Wizard. It will take care of most of the boilerplate code.
I do have a sample on writing custom encryption pipeline components, though my specific sample uses symmetric encryption and not RSA (but should give you a clue as to how to implement this). The code for these components can be found here.
Maybe this post we just uploaded can be of help: http://www.leandrodg.com.ar/blog/2010/03/encryption-and-decryption-with-x-509-certificates/

We have a project with a PWA where we want to implement client sided encryption. We wanted to use Webauthn as a second-factor in combination with passwords. In the background we use a randomly generated key to encrypt/decrypt the database, which is stored symmetrically encrypted with the password on the server. However I am struggling to find a good way to add encryption to this key with webauthn. My tries so far:
Using raw JS samples from https://webauthn.guide , however I cannot find a part which is always the same and could be used for symmetric encryption/decryption, even the public key changes when logging in with the same USB token multiple times (???)
Using fido2-lib from npm: I couldn't get the sample to work, since the sample is not well documented and pretty long
Using server-sided authentication like spring webauthn, however I do not want the server to know anything about the client.
Any suggestions how I could implement an encryption with webauthn?
The protocol as it stands does not provide generic public key crypto services as far as I am aware. The best you can do is prove that a user is in possession of the private key related to the public key you hold.
You can learn from the following github repo ,it has many Webauthn out of the box examples (see the tech it supports inside)
Here are some samples I found at github https://github.com/OwnID/samples
In addition,I read about FIDO ,Webauthn and passkeys at passkeys.com
Everything about this cool tech is there
Years after this question, the hmac-secret extension has arrived.
This extension binds a secret to a Webauthn credential. This secret can be used to decrypt or encrypt data on client side.
Another approach could be the use of the largeBlob to store a secret generated during the creation ceremony.
Note that the availability of those extensions depends on the authenticator that is used and may fail.
My case is that I want to make the data protected even from people who have access to the back-end (the keys store), so they couldn't read it without the user's (represented by the client app, in my case the browser) assistance.
One option is to have the decryption keys stored on the client and passed with each request which sounds pretty messy to me and i'm not sure I want my keys to wander around the net like this. What I imagine though is that the client will keep some token (it might be a password the user knows) and the decryption can't happen without it.
I thought about using the purpose string for this, I have the feeling it is not a good idea since its main purpose is isolation. On the other hand it is part of the additional authenticated data used for subkey derivation. (based on this article https://learn.microsoft.com/en-us/aspnet/core/security/data-protection/implementation/subkeyderivation?view=aspnetcore-2.1#additional-authenticated-data-and-subkey-derivation).
I came across some examples that create their own symmetric encryption with a lower level classes. (like this post Encrypt and decrypt a string in C#?). Since I'm not an expert in this area I would like to use as much build in classes as possible.
What is the recommended way to achieve what I need with the classes from the Data Protection API? (I'm using .net core 1.1 on Ubuntu)
I have a Java application (an ESB - Enterprise Service Bus) which deals with customer sensitive data and have a requirement of supporting Data encryption at rest in order to prevent data abuse.
The application stores customer data for processing on the file system and application interacts with it through java.io.File API. So basically, I need to encrypt the file before it is persisted on the file system by the application and then decrypt it before application reads it so that it can be parsed and processed.
Are there any good frameworks or libraries that can help me implement Data encryption at rest? I am planning to use PGP encryption/decryption for implementing Data encryption at rest.
I am looking for best and recommended approach for implementing Data encryption at rest within my Java application and any help shall be appreciated.
Why on Earth would you think pgp is the right tool for this? Seems to me that you only need a symmetric key solution, so pgp feels like the wrong answer.
Cryptography in Java is a minefield. Easy to do things wrong, hard to do things right.
Having said that, you have a better chance to not screwing up if you use BouncyCastle rather than something else. They have example code that shows you how to do various operations.
For encrypting data at rest, I recommend you use AES in either CBC mode or CTR mode. If using CBC mode, make sure you choose your IV in a cryptographic secure way (unpredictable). Also, never re-use an IV for any mode of operation.
You should also consider whether you need message integrity. General guidance about symmetric encryption here.
Even though people often get crypto wrong, the bigger problem is key management. That's a whole new can of worms (and don't be fooled into thinking pgp provides a solution to this: all it does is shifts the problem to somewhere else).
I've got an AS3 project that I've successfully added encryption to with the excellent as3crypto library. I've also got an AS2 project that I would like to add the exact same encryption to, with the AS2 version of as3crypto.
Unfortunately, AS2 doesn't have the excellent ByteArray class, so it hasn't been as easy to get working.
My basic process is this: Open a Socket connection, create an ARC4 object, encrypt data with the ARC4 instance before sending, decrypt incoming data with an ARC4 object when receiving. Straightforward.
In AS3 this is working great. How do I do the same thing in AS2? Is there an example of usage of the AS2 RSA library somewhere that I haven't been able to find? Anyone have any idea of how the ARC4 class is supposed to be used in AS2?
Here are examples:

I wonder which class is the class that I use to encrypt data (first time string data) and the best method of encryption (among those supported by caché). Must generate a strong encryption for data in my project.
Any help is welcome.
If someone can show me some example, I'll be even more grateful.
Please state what exactly do you want to encrypt. To encrypt the whole database, there is a setting in System Management Portal, this encryption is certified in US. To encrypt data transfers, you may use SSH (see %Net.SSH.*), HTTPS (see %Net.HttpRequest with Https property), and Web Services with WS-Security (see documentation). To encrypt just any string internally, see $system.Encryption.Help().
We use ensemble web services to serve up Base64 encrypted XML payloads to web portals and mobile apps in the healthcare field. The code we've implemented looks something like the below snippet, in addition to some other security features related to the web service.
Set sc = ..xmlData.XMLExportToString(.xml)
Set xmlReturn = ##class(%System.Encryption).Base64Encode(xml)
Quit xmlReturn
