* MD5 and SHA-1 are not collision resistant: use them for checksums only, never for signatures, certificates or anything an attacker can shape. A checksum from the same server as the download only catches transfer errors, not tampering.

HMAC with SHA-1 is still considered sound. The text and the key are never written to the address bar.
