Using the code at https://web.archive.org/web/20150612123348/http://blog.objectgraph.com/index.php/2010/04/20/encrypting-decrypting-base64-encode-decode-in-iphone-objective-c/ (the link that you provided in comment), you can encrypt your plist by:

NSData *plistFileData = [NSData dataWithContentsOfFile:plistPath];
NSData *encryptedData = [plistFileData AESEncryptWithPassphrase:password];
[encryptedData writeToFile:encryptedPath atomically:YES];

plistPath is a NSString containing the path to the plist file you want to encrypt
password is the encryption key you would like to use
encryptedPath is where you want to save the encrypted file

to decrypt:

NSData *encryptedData = [NSData dataWithContentsOfFile:encryptedPath];
NSData *plistFileData = [plistFileData AESDecryptWithPassphrase:password];
[plistFileData writeToFile:plistPath atomically:YES];

encryptedPath is a NSString containing the path to the encrypted plist file
password is the encryption key you would like to use
plistPath is where you want to save the decrypted plist file
