From Australia’s Guidelines for Cryptography:
For most purposes, a hashing algorithm with an output size of 224 bits provides 112 bits of effective security strength, with larger output sizes providing more bits of effective security stre… Continue reading Does it make sense to disallow SHA-224 and SHA-256 to defend against quantum computers?
I have created a pgp keypair and uploaded the public key to keys.openpgp.org.
It included my email address.
A government service has now verified my citizen ID and signed my pgp public key user id (proof that the name on my ID matches with… Continue reading How can I "update" a pgp public key on a keyserver with a new signature for one of the user id

I’m trying to make a device that will encrypt and store data. It should require a master password at startup, but then shouldn’t need anything else to decrypt the data throughout the lifetime of the program. It also should be secure, i.e. … Continue reading HSM for Secure Encrypted Data Storage
I have to generate a PGP keypair and share the public key with an external provider. Based on how we already handle it with RSA keypair, we are using the concept of trusted CA which issues certificate to share with providers instead of sha… Continue reading Create a certificate for a PGP key pair [duplicate]
Circom is a circuit language capable of generating zero-knowledge proofs, which involves some input signals and output signals. If all the input and output signals during the generation of the zero-knowledge proof are public, meaning that … Continue reading The issue of public/private signals when generating zero-knowledge proofs with Circom [migrated]
I know that TLS MitM can get HTTP/S traffic decrypted when using certificates.
I’m wondering if it has the ability to decrypt the Apple Airdrop protocol as well as it doesn’t go through a server and uses WiFi Direct to create a peer-to-pee… Continue reading Can a TLS MITM decrypt Apple Airdrop files?
Hi i’m wondering about the security differences between AES Key Wrap and simply encrypting the encryption key with AES-GCM-SIV. What are the advantages of using AES Key Wrap, and what is different under the hood?
Lets say we have an application WebApp where users input confidential data to be sent to Acme Inc’s secure enclave (AWS Nitro in this case) for processing, and the results of this processing are sent back to the WebApp for display.
What wo… Continue reading What is best practice cryptography when it comes to this scenario?
Its known that cipher is made with LFRS. Cipher text is 868 bits long, and its known that the plaintext starts with "Dear Student", therefore we can get the keystream of first 84 bits. However, we do not know anything about the l… Continue reading LFSR, starting with a known sequence [migrated]
