Algorithm Comparison

Compare different hash algorithms and their characteristics

Algorithm	Output Length	Security Level	Speed	Common Use Cases
MD5	32 chars	Low	Fast	File integrity, checksums (deprecated for security)
SHA-1	40 chars	Low	Fast	Git commits, legacy systems (deprecated for security)
SHA-256	64 chars	High	Medium	Bitcoin, SSL certificates, password hashing
SHA-512	128 chars	Very High	Slow	High-security applications, password hashing
CRC32	8 chars	None	Very Fast	Error detection, file verification

About Hash Functions

What are Hash Functions?

Hash functions are mathematical algorithms that transform input data of any size into fixed-size strings. They are deterministic, meaning the same input always produces the same output.

Key Properties:

• Deterministic output
• Fixed output size
• Fast computation
• Avalanche effect (small input changes = large output changes)

Security Considerations:

• MD5 & SHA-1: Deprecated for security use
• SHA-256: Current standard for most applications
• SHA-512: Higher security for sensitive data
• CRC32: Error detection only, not cryptographic

Common Applications:

• File integrity verification
• Password storage (with salt)
• Digital signatures
• Blockchain and cryptocurrencies
