I’m trying to understand how Kerberos works, in particular how the initial client sends a request to the Access Server. Some YouTube videos I’ve seen say the initial request is partially encrypted using the client’s password. First, what i… Continue reading How is the initial request made to the Access Server in Kerberos?
I am making a password manager and generator. The user creates the login information, and then I hash their password. After that, I generate the password and encrypt the password with a key stored unprotected. My Question is how do I prote… Continue reading Storing a key in a symmetric encryption for password manager using cryptography module
In my app i want to "encrypt" cryptography key on user’s password. As i understood the best solution is using PBKDF2 for this purposes. I found implementation in OpenSsl crypto library: PKCS5_PBKDF2_HMAC.
But there is some securi… Continue reading What is secure params for PBKDF2 (2021 year) [duplicate]

I read in some docs, there are several version of GPG key extension available.
For ex: gpg, ascii, p12
I know .gpg extension is in binary, and Ascii is in text.
But I want to know their differences regarding its quality and security.
So pl… Continue reading Key pairs extension / version
can we use the same key pairs, created by 1 encryption tool, for encryption decryption,
in another encryption tool ? for ex, created by hypercrypt, but being used in cryptermite,
or maybe within the same tool, but different version ? for… Continue reading Using same key pairs in several different encryption tools and version
I am trying to sign some data with a symmetric key AES128 on the TPM2. However, I get this error during the signing
ERROR: Unknown key type, got: 0x25
ERROR: bad signature scheme for key type!
ERROR: Unable to run tpm2_sign
primary key cre… Continue reading How can we use a symmetric key for signing data on TPM2.0?
I would like to know which method is more secured. I know that they can be combined, but I would like to understand why TPM or OpenSSL might be a more secure technique to generate (encryption, decryption) keys
I wrote an openssh-key-v1 Protocol reader and extracted all fields according to the format definition:
"openssh-key-v1"0x00 # NULL-terminated "Auth Magic" string
32-bit length, "none" # ciphername lengt… Continue reading How to convert 64byte openssh-key-v1 to the resulting 32byte ed25519 private key
Excuse me if this is obvious, but while encrypting one of my disks, I got bored and read the text on the window.
And the question came to me, how the heck can I move a mouse in a way that a computer couldn’t reproduce?
To be more specific… Continue reading How does collecting mouse movements increase cryptographic strength?
