MD5 & Base64
Hash or encode text in your browser.
MD5 produces a fixed 128-bit fingerprint of your input; Base64 re-encodes bytes as text so they survive systems that expect plain text. Both run in your browser. Base64 is encoding, not encryption — anyone can decode it.

How MD5 & Base64 works
What it does
Hash or encode text in your browser.
What you get
An MD5 digest or Base64 encoded/decoded text. MD5 is not secure password hashing.

What if a check cannot finish?
Confirm your input and try again. A timeout, blocked request, or unavailable provider is not proof that a domain is broken. Internet measurements and third-party services have limits.
MD5 & Base64 — frequently asked questions
Is MD5 safe for storing passwords?
No. MD5 is fast and has practical collision attacks, which is the opposite of what password storage needs. Use bcrypt, scrypt or Argon2 with a per-user salt.
Is Base64 a form of encryption?
No. It is a reversible encoding with no key. Anything Base64-encoded is readable by anyone who decodes it, so never use it to protect secrets.
What is MD5 still reasonable for?
Non-adversarial checksums: detecting accidental corruption, cache keys, deduplication. Anywhere an attacker might craft the input, use SHA-256 instead.
