The book "An Introduction to Mathematical Cryptography" by J. Hoffstein et al. talks about a three-line implementation of the RSA algorithm in Perl, which people used to protest US govern...

Is it possible to convert a PKCS#8 encoded RSA private key into PKCS#1? I know this can be done easily via openssl, but can it be done in Java?

I need to read in an RSA private key from a file to sign a JWT. I have found some examples on how to save a generated RSA key to disk but nothing showing how to build a key struct based on a pre-ge...

I need to generating a RSA and DSA key pair (public and private key) in PEM format using java. I want the public and private key files to be opened with this format: -----BEGIN PUBLIC KEY----- M...

I am getting the error given below when parsing the signature. Anybody has idea why the error is showing? Note that: Using the same certificate I signed my own XML and verified which is working...

As the title suggests, I would like to know if there is a way to encrypt and decrypt, using for example the RSA algorithm, data from javascript to dart and the opposite. I saw that there is a libra...

I'm sorry to ask your skills about a question asked so many times. I have an issue about RSA crypthography. I've already checked the other topics about this issue but i didn't find any helpful answ...

I'm using crypto/rsa, and trying to find a way to properly save and load a key. Is there a correct way to create a []byte from an rsa.PrivateKey. If so, is there a way to properly do so for an rsa....

(I am using MAC) My id_rsa starts with -----BEGIN OPENSSH PRIVATE KEY----- but I expect it to starts with -----BEGIN RSA PRIVATE KEY----- I have send my id_rsa.pub to server administrator to get ...

Is it possible to read the RSA private key of format PKCS1 in JAVA without converting to PKCS8? if yes, sample code is appreciated. -----BEGIN RSA PRIVATE KEY----- BASE64 ENCODED DATA -----END RS...

I want to generate an RSA public private key pair in powershell without using external software and I want to test it. It should be able to encrypt/decrypt data on any online public/private key ver...

Here is how Google suggests creating an Android keystore: keytool -genkey -v -keystore my-release-key.keystore -alias alias_name \ -keyalg RSA -keysize 2048 -validity 10000 While 10000 days may...

I did the factory reset, and my computer is newly installed. I enabled the USB debuging, and connect to the computer. It shows the drivers are installed successfully, and i can see so in the device...

This question is more generic rather than for a specific language, so I will explain my issue and what I have tried in pseudocode. I am trying to generate a PEM public key from a JWK Set. The JWK i...

I'm writing a command-line tool that will need to interact with a webservice, and I would like to be able to authenticate it using the user's ssh key. I'm wondering if I can do something like this:...

I'm trying to follow along the Upskillcourses.com web dev online course. In lesson 11 I'm supposed to link up cloud9 to github. I'm trying to get the SSH key. But it's not working: ec2-user:~/env...

It appears they are both encryption algorithms that require public and private keys. Why would I pick one versus the other to provide encryption in my client server application?

TL;DR: RSA public key generated in iOS and stored in the keychain, exported as base64 and sent to a java backend, is not recognized. I'm implementing a chat encryption feature in an iOS app, and I...

I am looking for a Java function that will get an RSA PrivateKey and will return the correct RSA PublicKey? Alternatively, is there a function that will tell us if the RSA PrivateKey/PublicKey is ...

I have an RSA public key modulus and exponent string. I want to create a OpenSSL::PKey::RSA from these two strings. Basically they come in as: n = 'long string' e = '4-character string' How w...
