- choosing argon2 parameters for keepass
- Java spring textencryptor is capable of taking 3 inputs, a text input, a password and a salt, if I keep the password and salt and input all the same, but just encrypt again, I get different ciphertext, how is that possible?
| Communicating information without revealing method Posted: 19 Mar 2018 05:17 PM PDT I have a real number, S, that I'm trying to communicate to a different party (say, across the world) in real time. S is the output of a Python script and varies with respect to time. Let party B represent the intended recipient. I need to provide B with a file which computes S. The issue is that the file that computes S is confidential, and I cannot allow B to read the code. Is it possible to allow B to perform some task whenever they want, without revealing how to perform the task? If so, how? [link] [comments]  |
| choosing argon2 parameters for keepass Posted: 19 Mar 2018 06:17 AM PDT I'm using keepassxc and recently it introduced the option to use argon2 , but what do you recommend to use its parameters? the default is 64 MiB of memory. I have a 2012 Intel i5 (2 cores , 4 threads ) . Another question: it also introduced chacha20, should I switch to that too ? or stick with aes256 ? or the twofish . thanks [link] [comments]  |
