PASSPROTECT subcommand (TCM MODEL command)

The PASSPROTECT subcommand saves an external file, that was specified on the DATA keyword of the OUTFILE subcommand, as an encrypted file. An encrypted file can be opened only by providing the correct password.

PASSWORD

Specifies the password that is 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 not to encrypt the file and is the default.

ENCRYPTEDPW

Specifies whether the password is encrypted.

NO

The password is not encrypted. It is treated as plain text. This option is the default.

YES

The password is encrypted. Use ENCRYPTEDPW=YES only when the password is known to be encrypted. Passwords are always encrypted in pasted syntax.

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.
