I have installed Fedora 24 on a micro sd card to test it, but it did not that I recall give me the option to encrypt during install. Is this my mistake?

I found during an install of Mint 18 that I could encrypt the home folder. What does this exactly mean? Is it the same across Linux?

An encrypted micro sd car, it will not be deletable right?

Encryption restricts access to specific data, not to the device itself. Anyone can take a micro sd card and write over the data contents, whether these are encrypted or not.

Generally, some of the benefits and costs of encrypting your /home directory are mentioned here: http://askubuntu.com/questions/37/wh...er-what-does-t

When it comes down to it, the major benefit of doing so is that if someone has physical access to the disk on which your /home directory resides, they cannot read your data without knowing your login password. The main costs are a possible slightly degraded performance and a potentially more difficult recovery procedure if /home becomes corrupted (a problem which will be minimised by regular backups).

Personally, I don't encrypt /home, ensuring instead that any sensitive data is encrypted using other means (VeraCrypt etc.). However I may be in the minority here.

erm. it sounds like you're saying the Login password = encryption password?

On Ubuntu/Mint, if you choose to encrypt your home directory, then the default is that your login password is the one used to encrypt/decrypt your home partition. So, that's what I'm saying, yup.

An encrypted Manjaro install this same micro sd card, when inserted could not be read. 32 GB appeared to be like 3 MB. I had to use killdisc to erase it.

I am new to considering encrypting home and data partitions. What are some thoughts?

Mint. nuff said.
