We may consider:
- symmetric-key algorithm vs. asymmetric key algorithms (public-key cryptography)
- Diffie--Hellman key exchange is a specific method of exchanging keys.
- Ensure integrity e.g. by hash-codes
- Key file handling could be optimized in different ways.
- Please keep in mind that unencrypted data is in RAM (see PDI-6170 for a circumvention to prevent heap dumps)
- Beneath the binary or indexed storage type, an encrypted storage type may be possible in Kettle core.
