Preguntas Frecuentes

Why is SHA1 40 characters long?

SHA1 produces a 160-bit output. When represented in hexadecimal (base 16), each character represents 4 bits, so 160 / 4 = 40 characters.

Is SHA1 still used today?

Yes, widely in version control (Git) and non-cryptographic checksumming. However, strictly for security and digital signatures, it has been deprecated in favor of SHA-256 due to collision vulnerabilities detected in 2017.

How does it differ from MD5?

SHA1 produces a longer hash (160-bit vs 128-bit) and was designed by the NSA to be stronger than MD5. While both are now considered cryptographically weak for high-security uses, SHA1 is historically the successor to MD5.
