Silver Key editions

Silver Key edition comparison

Choose which Silver Key editions fits your requirements best:

  • Free Edition is excellent choice for those users who use encryption only occasionally. While it lacks bells and whistles of the more advanced editions, it still does the job perfectly and provides the same highest level of security.
  • Standard Edition includes all the major features you'd expect from top-notch encryption software. Besides basic encryption/decryption operations, this edition includes advanced features such as Parcel Designer or support for binary keys.
  • If security and reliability is a priority, Enterprise Edition is what you need. In addition to the Standard Edition's features, Enterprise Edition offers command-line interface for automated processing and can work in FIPS 140-2 -compliant encryption mode.

Unlimited file size

While Silver Key does not limit file size, operating system limitations may apply. For instance, FAT32-formatted drives cannot hold files larger than 4Gb. In addition, the system will likely refuse to run a very large executable parcel (you can decrypt such a parcel by right-clicking it and selecting 'Decrypt').

Additional ciphers and Free Edition

Free Edition does not allow cipher selection and always uses AES for encryption. However it includes all the additional ciphers from the advanced product editions, and so can decrypt parcels created by Standard or Enterprise editions.
