How do I encrypt local file in Solaris ? On Linux I use either OpenSSL or GPG but these are both open source projects not native in Solaris land. For this Solaris has encrypt/decrypt which do what their name say.
And of course we talk here about symmetric encryption. Options for encrypt/decrypt are succinct – list available algorithms, specify input/output file(s), and optional specify file containing the key or otherwise type it on terminal. Few examples are to follow.
– List algos
# encrypt –l
Algorithm Keysize: Min Max (bits)
——————————————
aes 128 256
arcfour 8 2048
des 64 64
3des 192 192
——————————————
aes 128 256
arcfour 8 2048
des 64 64
3des 192 192
- Now let’s encrypt something (file smtp_send.py ) with AES algo .
# encrypt -a aes -i smtp_send.py -o smtp_send.py.enc
Enter key:
Enter key:
Solaris#
Solaris# file smtp_send.py.enc
smtp_send.py.enc: data
- And what about decrypting ?
# decrypt -a aes -i smtp_send.py.enc -o smtp_send.py.dec
Enter key:
Enter key:
- In case you wish to use key stored in a file (I personally don’t do it as it is too easy to forget to delete the key file).
# encrypt -a aes –k key_in_a_file.txt -i smtp_send.py -o smtp_send.py.enc

What do you do with Enter Key: ?
if I leave it blank it reads “encrypt: invalid key”
You enter passphrase you want this file to be encrypted with
In this case you encrypted a *.py file, and supposing this was a readable file or directory, when you decrypt into *.dec, how would you then go and get the readable file or contents of the directory?
