PASSPROTECT Subcommand (SAVE CODEPAGE command)
The PASSPROTECT
subcommand specifies the settings for saving a data file as an
encrypted file. Once encrypted, the file can only be opened by providing the correct
password.
PASSWORD. Specifies the password required to open this file. Passwords are limited to 10
characters and are case-sensitive. The specified value must be enclosed in quotation marks. The
keyword NONE
specifies that the file will not be encrypted and is the
default.
Warning: Passwords cannot be recovered if they are lost. If the password is lost the file cannot be opened.
ENCRYPTEDPW Keyword
The ENCRYPTEDPW
keyword specifies whether the password is encrypted.
NO. The password is not encrypted. It is treated as plain text. This is the default.
YES. The password is encrypted. Passwords are always encrypted when pasting syntax from
the Save Data As dialog. Note: ENCRYPTEDPW=YES
should only be used when
the password is known to be encrypted.
Creating strong passwords
- Use eight or more characters.
- Include numbers, symbols and even punctuation in your password.
- Avoid sequences
of numbers or characters, such as
"123"
and"abc"
, and avoid repetition, such as"111aaa"
. - Do not create passwords that use personal information such as birthdays or nicknames.
- Periodically change the password.
Note: Encrypted data files and output documents cannot be opened in versions of IBM® SPSS® Statistics prior to version 21. Encrypted syntax files cannot be opened in versions prior to version 22.
