Java edtFTPj/PRO version and support questions

Question

Hi

For the edtFTPj/PRO (our purchased version is 4.4.0), we have the following questions:

1. What SFTP versions are supported? Our client is asking for 3, 4, and 6.

2. Does it support AES-256 block cipher in CTR mode (preferred) or CBC mode (fallback)? (I know it does support AES-256, but I'm unfamiliar with the details like CTR mode/CBC mode)

3. Support for SHA hashing algorithms? (pretty sure it is supported but I had trouble confirming what is supported..)

Thanks

Answer 1

1. Currently SFTP 3 only.

2. Yes, AES-256 CTR is supported in SFTP.

3. Yes, SHA hashing algorithms are supported. The question probably means SHA-2, which is supported in FTPS and SFTP in different ways.
