one time secret represents a topic that has garnered significant attention and interest. Can we trust onetimesecret? - Information Security Stack Exchange. So for example you ask the other person to use the place you met for the first time as a password for the first layer. Then you ask them something else for the second one and so on, until you are confident only the correct person could know all the answers. secret sharing - Best method to send credentials to clients ....
I'm constantly exchanging credentials with my clients for things like database servers, cloud accounts, etc. Neither I nor my clients, have time to implement a sophisticated method for secure How can I decode a message that was encrypted with a one-time pad?.
The question was, how can you decrypt a message that was created from one time pad, pretty sure that hasn't been answered yet. Originally the one time pad was used with just characters, and is very basic. Can a Time-based One-time Password (TOTP) key be decoded from generated .... The HMAC-based One-Time Password (HOTP) algorithm (RFC 4226 (informational)) that forms the foundational part of TOTP says that the shared secret should be at least 120 bits in length, and recommends 160 bits for its key. authentication - How does Google Authenticator work? Google Authenticator supports both the HOTP and TOTP algorithms for generating one-time passwords.
With HOTP, the server and client share a secret value and a counter, which are used to compute a one time password independently on both sides. From another angle, overlap for One-Time Passwords - Information Security Stack Exchange. Additionally, the core idea behind an One Time Password is that an algorithm generates a short, ephemeral password as a way to provide a second factor. In this case, the factor is something you have, i.e.
the secret code that can be used to seed this algorithm. the generated value is derived from that seed value and the current time. Moreover, what is the simplest safe way to convey a password to another person .... "One time secret" does a good job, but it does depend on you trusting the site. Deciding whether to use it depends on the information that you sending.
authentication - one-time JWT token with JWT ID claim - Information .... And the jwt itself is one-time too, because once the password is changed, the jwt won't be verifiable any more. In this context, which is "better" than the approach you've detailed, because a server-wide secret key isn't needed for this use case. Whats the safest way to store 2fa/mfa secret key in database?. For one thing, the server only sees the user's public key, which is only usable for verification; the secret that the user uses to authenticate never touches your server at all.
Moreover, diffie hellman - Why not use symmetric encryption? Any time you want to contact someone new using symmetric encryption, you have to " tell them [the shared key] in person, read it over the phone, use One Time Secret," etc.
