kandi X-RAY | tink Summary

tink is a Java library typically used in Security, Cryptography applications. tink has no bugs, it has no vulnerabilities, it has a Permissive License and it has high support. However tink build file is not available. You can download it from GitHub, Maven.

Using crypto in your application shouldn't have to feel like juggling chainsaws in the dark. Tink is a crypto library written by a group of cryptographers and security engineers at Google. It was born out of our extensive experience working with Google's product teams, fixing weaknesses in implementations, and providing simple APIs that can be used safely without needing a crypto background. Tink provides secure APIs that are easy to use correctly and hard(er) to misuse. It reduces common crypto pitfalls with user-centered design, careful implementation and code reviews, and extensive testing. At Google, Tink is one of the standard crypto libraries, and has been deployed in hundreds of products and systems. To get a quick overview of Tink design please take a look at slides from a talk about Tink presented at Real World Crypto 2019.

QUESTION

Filtering with a multi-select menu

Asked 2022-Mar-25 at 00:51

So I have a select menu that lets the user select multiple options. the selected options correspond to actorModel. Then I have an object array and I wish to filter it according to the selected options. If the user selected option A and B , then it will return two objects from actorDocs. The one that has a label value 'A' and the one that has the label value 'B'. If no option is selected (actorModel is null) then it will return all objects from actorDocs.

The problem I am encountering in this code is that it only works if the user selects one option. If the user selects more than one, then I tink it is trying to locate an object that has several labels instead of several objects with each label.

Any help is more than welcome

Iterate through multiple elements of querySelectorAll with forEach

The problem is as following: I have created a separate JS file, in which I want to iterate through elements belonging to a certain class audioz. In the second line of my JS code I use the addEventListener on item, however the code does not seem to work with item, only if I put document, but the result remains flawed. What am I doing wrong in the iteration?

ANSWER

Answered 2022-Jan-16 at 16:07

You are currently adding a keydown event listener to each audio tag. However, the audio tag is hidden, so you can't execute the keydown event on it. Thus, your code will not work.

Add the event listener to the document instead.

security-crypto: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent

Asked 2021-Nov-29 at 13:23

Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent. Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

GCP Cloud KMS - custom key, disaster recovery possible?

Asked 2021-Nov-29 at 10:39

we are currently getting our heads around gcp cloud kms and how to cater for disaster recovery. this is our current test setup:

Java using Spring boot + Google Tink using KMSEnvelopeAead + AesGcmJce (i.e. generated DEK by tink that will be encrypted via kms (KEK) and stored alongside the ciphertext), symmetric

project "A" (the initial project before disaster recovery)

-> KMS -> keyring "keyringABC" -> key "keyABC" -> imported custom key via import job. i can successfully encrypt/decrypt some text - all fine, all good

...

ANSWER

Answered 2021-Nov-29 at 10:39

Yes, it has to be the exact same key with the exact same resource id including project id.The ciphertext for decryption should be exactly as returned from the encrypt call. So, you need to make sure it matches the project in which you created the KMS key. When you try to decrypt the data with the newly created key from project-B that was encrypted in project-A, it fails.

In your use-case the ciphertext you're trying to decrypt was encrypted using a different key. You should use the same key for both encryption and decryption, else KMS tells you that it could not find the key while actually the key was found.

The problem is the following: I want to program it without using (nearly) duplicate code and therefore I had the idea of using generics.

Assuming you're sure the stack will always be in the order you expect here (which you seem to be).

Instead of a generic stack (which I believe limits you to only one value of T), you could use a stack of Object and cast the results of the peek() function.
