Robo-FTP User's Guide > Appendix > Security > Supported Encryption Technologies

Robo-FTP supports encryption and decryption of files using PGP (Pretty Good Privacy) through the PGPENCRYPT and PGPDECRYPT commands. PGP cryptography enables you to protect sensitive information when it is stored locally or transmitted across the Internet, so that it cannot be read by anyone except the intended recipient. Robo-FTP's PGP implementation includes support for the following features:

Supported Symmetric Ciphers:

AES (128-bit)

AES192

AES256

IDEA

CAST5

Blowfish

Twofish

3DES

Supported Key Algorithms:

RSA (1024-, 2048-, and 4096-bit)

DSA (1024-, 2048-, and 4096-bit)

Elgamal

Supported Hash Methods

MD5

SHA1

RIPEMD160

SHA 256-bit, 384-bit, 512-bit

SHA-224

Supported Compression Algorithms:

Uncompressed

ZIP

ZLIB

BZIP2

Robo-FTP can generate its own PGP keys, so no additional software is needed when working with PGP encryption. When generating a new PGP key with Robo-FTP you can choose between the RSA or the DSA (aka DSADH, aka DSS) algorithms, at either 1024-, 2048-, or 4096-bit lengths. By default, files encrypted Robo-FTP use the AES(-128) cipher (or IDEA in PGP 2.6 compatibility mode), ZIP compression, and SHA-1 hash (or MD5 in compatibility mode). Only the IDEA cipher is supported in PGP 2.6 compatiblity mode.
