Even in "secure mode", your passphrase must be sent to backblaze's servers whenever you do a restore. They then have posession of decrypted version of your files for a while. This is unacceptable. As brianwski wrote in https://news.ycombinator.com/item?id=8169040 https://news.ycombinator.com/item?id=8169040: ...[I]f you lose a file, you have to sign into the Backblaze website and provide your passphrase which is ONLY STORED IN RAM for a few seconds and your file is decrypted. Yes, you are now in a "vulnerable state" until you download then "delete" the restore at which point you are back to a secure state.
