how to encrypt a folder

I have some bank login details I wish to put in a folder and access via a  password for security reasons and wondered how i could do that ?

Create an encrypted disk image:

Disk Utility for Mac: Create a disk image using Disk Utility

Hi Angloargie:

See the following to make a password protected folder:

You can make a password-protected disk image, that starts out small but increases in size as you put files into it.

To make an encrypted Sparse Disk Image:

Open Disk Utility and select File > New Image > Blank Image.

In the popup under Save As, give the sparse image file a name. i.e. “My Secret Stuff”.

This filename will be what you double-click on to make the virtual disk appear.

Under Name, give it a name like “My Secret Stuff” or something different if your prefer.

From the Size pop-up menu, choose the maximum size this disk image can grow to.

The disk image starts out small and slowly increases in size as necessary up to the max. size.

From the Format pop-up menu, choose OS X Extended (Journaled)

From the Encryption popup menu, choose one of the two encryption methods that will password protect your disk image. The recommended is “128-bit AES encryption”.

From the Partitions pop-up menu, choose Single partition - GUID Partition Map

From the Image Format pop-up menu, choose “sparse disk image”.

Click Create. Make up a password (type it twice). Then click Create.

Now on your desktop should be a disk image file with the ending “sparseimage” .

It will occupy xx MB on your hard disk to start with.

Double-click on it and enter your password to open the encrypted virtual disk on your desktop. You can know put private files in the disk image. The sparse image will grow in size automatically as you add files to it.
