I want to encrypt a 100 GB file on my up to date iMac. It is hard to find out where the temp file is, so I can't find out the progress, but the encryption is already taking a full day. Is this normal? What encryption speed (MB/min) can I expect with a normal machine?
I am currently using mcrypt (from macports) with the command mentioned in the manual for linux crypt compatibility. Is this a good/secure algorithm? Should I use another?
mcrypt -a enigma --keymode scrypt --bare Backup.tar
I want to do backups regularly and encrypt them, so any help is really welcome!
Had the question first on cryptography, but got redirected here.
for anyone interested, after we figured out that mcrypt froze I tried the following command and get around 1GB/min: openssl enc -aes-256-cbc -in Backup.tar -out Backup.ossl – Marian – 2014-06-07T18:43:25.950
