How do we use a mnemonic list of words as a seed (like we have been become accustomed using cryptocurrency wallets) to be able to recover a private key in case it gets lost, accidentally erased, or stuck on a broken device? This could be useful for e2e encryption between clients: the keys are supposed to be generated on the

RSA-SHA1 signature differs in JavaScript and PHP
I need to create a RSA-SHA1 signature in nodeJS, I am using the following code I’m double checked that my code result is true, I have same result with online tools if I select sha1WithRSA algorithm and I also get same result in PHP when I use openssl_sign function I need to sign data for a bank API, Unfortunately they
Why I can’t use RSASSA-PKCS1-v1_5 to encrypt/decrypt?
First of all, I’m completely new to cryptography and I just have basic knowledge about some encryption algorithms and how they work such as RSA, DES and so on. I want to use SubtleCrypto in JS to do some stuff including signing, verifying, encrypting, decrypting using RSA. I’m just unable to produce a key pair for doing all of them;
How can I use publicExponent as 65537 in RSA-OAEP algorithm in JavaScript?
Actually, I am using RSA-OAEP with SHA-256ANDMGF1PADDING for encryption and decryption in JavaScript using Web crypto API. The actual scenario I need to do is in java I am able to encrypt and decrypt using a public and private key with the same algorithm specifications. but there it uses a 65537 public exponent .now what I need to do is
RSA Encryption Javascript
Can anyone please help me with this – I have been instructed to write an application that takes some data then encrypts it with an RSA public key. It apparently needs to be “RSA encryption” (I have never heard or seen this before?) Which encryption cipher is RSA meant to use as standard? Answer Never mind found the answer myself!
