Frequently Asked Questions
What is SHA-1 used for?
SHA-1 is commonly used for checksums, data integrity verification, and in legacy systems. However, SHA-256 is recommended for new applications.
Is SHA-1 secure?
SHA-1 is considered cryptographically broken and should not be used for security-sensitive applications. Use SHA-256 or SHA-512 instead.
How long is a SHA-1 hash?
A SHA-1 hash is 40 hexadecimal characters long (160 bits = 20 bytes = 40 hex characters).
