MD5 hash algoritması ile verilerinizi hash edin

Security Warning

MD5 kriptografik olarak güvensizdir. 2004 yılında çarpışma saldırıları bulunmuştur ve modern uygulamalarda kullanılmamalıdır. Parola hashleme veya dijital imza için asla kullanılmamalıdır.

Önerilen alternatifler: SHA-256, SHA-512 veya BLAKE2

MD5 About

MD5, MD5 (Message Digest 5), an old cryptographic hash function developed by Ron Rivest in 1991. Collision attacks were found in 2004 and it is considered insecure for cryptographic purposes.

Technical Specifications

Hash Length:
128 bit (32 hex characters)
Block Size:
512 bit
Maximum Message Size:
2^64 - 1 bit
Status:
Insecure - Should NOT be used for cryptographic purposes

Usage Areas

  • File integrity verification (non-cryptographic purposes)
  • Legacy systems and applications
  • Download verification (as non-cryptographic checksum)

Features

  • Fast computation: Simple and fast algorithm
  • Deterministic: Same input always produces the same hash

Standards and References

  • RFC 1321 (deprecated)

⚠️ Important Warnings

  • Cryptographically insecure: Vulnerable to collision attacks (collision found in 2004)
  • Vulnerable to preimage attacks
  • Should NOT be used for cryptographic purposes
  • Modern applications should use secure algorithms like SHA-256, SHA-3, or BLAKE2
  • NEVER use for password hashing
  • NEVER use for digital signatures
