Default Security Levels:
1) DoD Level C = 1 pass, secure, fastest
This deletion method deletes the file pointer from the file table and overwrites the original file data with a single character (0x0).
2) DoD Level D = 1 pass, more secure, faster
This deletion method deletes the file pointer from the file table and overwrites the original file data with 3 characters (0x0, 0xFF, and one other random character).
3) Shell Level = 2 passes, most secure, fast
This deletion method deletes the file pointer from the file table and overwrites the original file data with 3 characters (0x0, 0xFF, and one other random character), then does it again on the second pass.
Custom security levels can be created in the Security section of Preferences. A user can define which characters to use for overwriting and specify the number of passes.
