Detailed Description
Password-based decryptor.
Crypto++ 5.6.5 and earlier used the legacy algorithms, including DES_EDE2 and SHA1. Crypto++ 5.7 switched to AES and SHA256. The updated algorithms are available with the Default* classes, and the old algorithms are available with the Legacy* classes.
The documentation for this struct was generated from the following file:
