I agree regarding most scenarios and I changed the text now. However, it's hard to keep the text understandable for average user and mention all relevant dangers without goind too much into details. So, I suggest this new version. Added below for review; I consider uploading this to Experimental and submitting for l10n in a couple of days. Regards, Eduard. Template: encfs/security-information Type: error _Description: Encfs security information According to a security audit by Taylor Hornby (Defuse Security), the current implementation of Encfs is vulnerable or potentially vulnerable to multiple types of attacks. For example, an attacker with read/write access to encrypted data might lower the decryption complexity for subsequently encrypted data without being noticed by the legimitate user, or may compute encryption information by timing analysis. . Until these issues are resolved, encfs should not be considered a safe home for sensitive data in certain scenarios.
