kandi X-RAY | jacs Summary

jacs is a Java library typically used in Security, Encryption applications. jacs has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

Jacs is a Java library and command-line tool for encrypting streams and files using a passphrase, including support for PBKDF2, SCrypt, BCrypt, AES, Explicit IV, and HMAC-based integrity checking. Jacs extends the Java CipherInputStream and CipherOutputStream classes to support Explicit IV and HMAC integrity checking. Jacs is integrated with common key derivation algorithms, including PBKDF2, SCrypt, and BCrypt. Jacs supports AES out-of-the-box via JCE. Other cipher algorithms can easily be added if the Bouncy Castle library is present. Key Derivation: PBKDF2, SCrypt, or BCrypt, caller may choose key derivation algorithm strength. Cipher algorithms: AES-256-CBC with PKCS5 Padding. Other algorithms can easily be added if the Bouncy Castle crypto library is present. IV: Explicit, never reused, generated from strong PRNG. HMAC: SHA256 (using encrypt-then-MAC approach, where leading IV + all ciphertext is signed).

Loading Vue component based on (changeable) variable

Asked 2021-Mar-14 at 18:05

total newbie with Vue.js here, so sorry if I'm missing something obvious.

I want to load components based on the content of a variable - so if the content of my variable changes, I want the component to change accordingly. I have all components imported (e.g. import Project1 from "@/components/Project1";), which again is saved in components: {'p1': Project1}

I use with goTo.page being defined in data as data() {return {goTo: {page: "p1"}}}. The problem seems to be the reactivness of goTo.page. I update it via this.$set(this.goTo, "page", "p2");. When running, i get the error Uncaught TypeError: Cannot read property 'page' of undefined, which I honestly don't understand, since its initialized with "p1".

QUESTION

Variable size for input parameter array

Asked 2020-Jul-14 at 19:55

To give you a bit of a background, I am trying to maximize the total coverage by a satellite constellation. So what I basically do is estimate the initial state vector for every satellite, propagate them over a period of time and co-relate the area covered with my area of interest and estimate the coverage. The initial state vector is an array of 6 elements (3 position + 3 velocity). So if I have 2 satellites then the array will have 2 rows and 6 columns. The below simple test script mimics the same data flow and formulation of my actual code to calculate the initial position.

There are two basic options:

Make the number of satellites an argument to your group, and allocate the correct sized arrays. Then run a separate optimization for each value of N and pick the one you like the best.
Allocate the arrays for the maximum possible number of satellites you want to consider, and add an additional blanking array as an input to turn certain ones on and off. Then you can use either a mixed integer approach or try some relaxation based approaches and treat the blanking array as real numbers.

I would personally chose option 2 for a couple of reasons. I would think the relaxation based approach would be more effective for larger numbers of N (MINLP are very hard to solve well). Also, its the most flexible approach, since you don't need to re-allocate anything. You can just adjust the values of the active array accordingly and turn things on an off at will.

Here is some updated code where you can do either method:
