FAQ - Frequently Asked Questions
What is SHA-1?
SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function that generates a 160-bit (20-byte) hash value, commonly rendered as a 40-digit hexadecimal number.
Is SHA-1 Secure?
SHA-1 is considered broken for many cryptographic purposes and is no longer recommended for secure applications. Stronger algorithms like SHA-256 or SHA-512 are advised for secure cryptographic operations.
Hash Details
SHA-1 produces a 160-bit hash value, which is typically rendered as a 40-character hexadecimal string.
- Length: 40 hexadecimal characters (160 bits)
- Speed: SHA-1 is designed to be computationally efficient, though its security has been compromised in recent years.
Example: Consider the SHA-1 hash
a9993e364706816aba3e25717850c26c9cd0d89d. This hash
consists of 160 bits represented as 40 hexadecimal characters.
What is Password Hashing?
Password hashing is a security technique used to transform a password into a fixed-size string of characters, which is designed to be impossible to reverse. It helps protect the password's original text while verifying user credentials without storing the actual password.
