Our standard plan includes BlowFish 128-bit and AES-128 and AES-256 bit encryption. BlowFish is selected as default encryption in OpenVPN by OpenVPN creators. AES encryption is used on many web sites on the internet as a standard and it is recommended and approved by NSA (think why!).
CryptoPlus is a set of more secure encryption algorithms supporting up to 512-bit encryption. CryptoPlus can be used with Astrill OpenVPN protocol only. CryptoPlus encryption algorithms are not endorsed or affiliated by NSA in any way. Currently we offer these encryption algorithms with CryptoPlus:
BlowFish 256-512-bit, CAST 128-512 bit and Camellia 128-256 bit. CAST is used in PGP software and Camellia is Japanese and European encryption standard.
