Sorted by: 5. To start with, it's certainly not a bad idea to avoid SHA-1 when other algorithms exist, which do not have the SHA-1 weaknesses to anyone's knowledge. The security of SHA-1 depends on how you're using it. The vulnerability is what's known as a collision vulnerability: an attacker has the ability to create two input ...

WebJan 4, 2016 · crypto provides a simple interface to symmetric Gnu Privacy Guard (gpg) encryption and decryption for one or more files on Unix and Linux platforms. It runs on top of gpg and requires a gpg install on your system. Encryption is performed with the AES256 cipher algorithm. WebOct 11, 2024 · 1. There is no "SHA1 with RSA encryption" for certificates used in SSL. In the context of certificates the owner of the certificate has a key pair (RSA, ECC...) and here the public key part is included in the certificate, SHA1 (or other hash algorithms) are used as a cryptographic hash within the signature and the private key (RSA, ECC..) of ...
WebAug 29, 2015 · That's multiprime RSA pushed to the max. The potential speedup is considerable. For small k, and standard arithmetic (quadratic multiplication and modular reduction) the speedup compared to normal RSA with CRT is in the order of k 2 / 4; that won't quite scale up to k = 64, but we can get a speedup by a factor like 300 or more (justified … WebJan 24, 2024 · Thank you again. Yes hashfunctions and asymetric crypto are tools which rely on different assumptions, however often used in combination. AFAIK the SHA1withRSA is mandatory for Android apk signing. at least for the v1 signatures. So youre indicating that its mandatory for Signal to have an highly vulnerable distribution mechanism?
