Quick summary
Crypto Stuff is a free, portable Windows utility that bundles a wide range of cryptographic tools. It provides hashing, symmetric encryption, and public-key operations (RSA and elliptic-curve), plus handy key-format conversion. The program is aimed at users who need a compact, no-install toolbox for common cryptographic tasks.
Hashing algorithms available
- BLAKE family algorithms
- RIPEMD variants
- MD series (e.g., MD5)
- SHA family (multiple SHA versions)
These options let you verify data integrity across many common hashing families.
Encryption and cipher options
- Stream cipher support for real-time or streaming protection
- Block cipher modes for file and data-at-rest encryption
Both types are included so you can choose the most appropriate method for transmission or storage needs.
Public-key features and key handling
- Elliptic-curve cryptography tools for modern asymmetric operations
- RSA key creation and general RSA operations
- Conversion utilities to switch RSA keys between DER and PEM encodings
This section makes it straightforward to generate keys, perform cryptographic operations, and convert key files for compatibility.
Usability and portability
Crypto Stuff runs without installation and provides a straightforward interface, making it convenient for technicians and users who need portable, reliable crypto utilities on Windows machines.
Alternate recommendation
