MD5 integrity checks for files
Generate a checksum for installers, firmware, or backups, then compare the digest against a trusted source. MD5 helps detect corruption or tampering during transfer.
For high-assurance security or collision resistance, consider stronger algorithms such as SHA-256, SHA-3, or BLAKE3—planned additions to CipherTools.
