Entering a password to sign in to your AOL account can sometimes feel like a hassle, especially if you forget it. If your smart device is enabled with biometric authenticators like a fingerprint sensor or facial recognition technology, you can sign in with ease. Enable biometric sign in
SHA-1: A 160-bit hash function which resembles the earlier MD5 algorithm. This was designed by the National Security Agency (NSA) to be part of the Digital Signature Algorithm . Cryptographic weaknesses were discovered in SHA-1, and the standard was no longer approved for most cryptographic uses after 2010.
The primary threat to the security of a fingerprint is a second-preimage attack, where an attacker constructs a key pair whose public key hashes to a fingerprint that matches the victim's fingerprint. The attacker could then present his public key in place of the victim's public key to masquerade as the victim.
Nobody has been able to break SHA-1, but the point is the SHA-1, as far as Git is concerned, isn't even a security feature. It's purely a consistency check. The security parts are elsewhere, so a lot of people assume that since Git uses SHA-1 and SHA-1 is used for cryptographically secure stuff, they think that, Okay, it's a huge security feature.
Intel SHA Extensions are a set of extensions to the x86 instruction set architecture which support hardware acceleration of Secure Hash Algorithm (SHA) family. It was specified in 2013. [1]
An HSM in PCIe format. A hardware security module (HSM) is a physical computing device that safeguards and manages secrets (most importantly digital keys), and performs encryption and decryption functions for digital signatures, strong authentication and other cryptographic functions. [1]
A browser fingerprint is information collected specifically by interaction with the web browser of the device. [ 1 ] : 1 Device fingerprints can be used to fully or partially identify individual devices even when persistent cookies (and zombie cookies ) cannot be read or stored in the browser, the client IP address is hidden, or one switches to ...
SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. [3] [4] They are built using the Merkle–Damgård construction, from a one-way compression function itself built using the Davies–Meyer structure from a specialized block cipher.
