About this tool
Inspect legacy DES and two- or three-key 3DES encryption/decryption.
Common uses
- Inspect legacy DES and two- or three-key 3DES encryption/decryption.
- Choose cipher, ECB/CBC mode, padding and input/output encodings.
How to use it
- 1.Choose cipher, ECB/CBC mode, padding and input/output encodings.
- 2.Enter data and an 8/16/24-byte key; CBC additionally needs an 8-byte IV in the selected input encoding.
Limits and notes
- Input is limited to 1 MiB. Without padding, data must align to 8-byte blocks. These legacy ciphers and unauthenticated modes should not be chosen for new sensitive-data protection.
