All your encryption needs are provided as free software on all Macs from OS X Lion to macOS Catalina. These kinds of encryption tools have typically only been accessible via the terminal or command line. Now, just a few extra clicks are all that is required to add an encrypted folder to my Mac. FileVault is a perfect encryption software designed specifically for the users of Mac, making it one of the best free Encryption software for Mac on which one can lay their hands on and have a convenient.

OpenPGP is the most widely used email encryption standard. It is defined by the OpenPGP Working Group of the Internet Engineering Task Force (IETF) as a Proposed Standard in RFC 4880. OpenPGP was originally derived from the PGP software, created by Phil Zimmermann.
Email encryption
Although OpenPGP’s main purpose is end-to-end encrypted email communication, it is also utilized for encrypted messaging and other use cases such as password managers.
For all operating systems

OpenPGP is available for all major platforms, such as Windows, Mac OS, GNU/Linux, Android, and iOS.
Standing the test of time
- Concealer is a file encryption program specifically for Apple Mac computers. Rather than encrypt all files on your harddrive, instead it provides an encrypted area for you to drag files into.
- This software is best USB encryption software window 2021 and now this software is updates and improved version of truecrypt. This software uses 3 different encryption algorithm like AES 256-BIT, Serpent and TwoFish.
- You’ve received encrypted file and you need to read the contents, maybe update it and encrypt and send it back; In all these scenarios you also need to make sure sensitive information will not remain in un-encrypted state. Now let’s see what it takes to achieve this using PGP Tool versus Average PGP software (LESS actions - better).

OpenPGP was standardized in 1997 and since then continuously improved. As far as we know, intelligence organizations aren’t able to break it.
This page lists free encryption / cryptographic software of a wide variety. There are free on-the-fly disk encryption / on the fly file encryption (OTFE)software that transparently encrypts files on your disk drive (or partition), on demand encryption tools that allow you to encrypt single files forthose one-off occasions when you need encryption public key encryption which is particularly useful for things like email (where the key youuse to encrypt your data is different from the key used to decrypt the data), etc. Included here are also software that can perform steganography,a sort of invisible encryption, where the plaintext version of your sensitive data is encrypted and hidden inside another file (typically imagesor sound or video files).
Caution: Be careful when you use cryptographic / encryption software that do not tell you which algorithm they use. Claims like'strong encryption', 'military encryption' and 'secure encryption' do not tell you very much — after all, anyone can simply convert theletters on (say) this page to numbers (where a=1, b=2, etc) and still claim it is strong encryption / cryptography. Of course I doubt any program uses suchkindergarten tricks. Nonetheless, words like 'proprietary encryption' should set you on your guard, and words like 'unbreakable encryption' should make youvery suspicious. In general, publicly available encryption algorithms like Rjindael AES tend to be better tested with the weaknesses and strengths knownthan some obscure proprietary algorithm that might well turn out to be a snake oil product. Note that this is not a comment on the qualityof any of the products listed here — it's just a generally well-known cautionary note.

Free On the Fly Disk / File Encryption (OTFE)
VeraCrypt is a fork (or spin-off, in layman's language) of TrueCrypt (see elsewhere onthis page), a now-defunctencryption software. Like its predecessor, it allows you to create a file on your hard disk that Windows treatsas an ordinary disk drive. Files stored on that virtual drive will be automatically encrypted or decrypted as necessary.It can also encrypt an entire hard disk, including your system drive.
[Update: the original site seems to have disappeared. I've put a link toa mirror site.]FreeOTFE is an open source OTFE (on the fly disk encryption) software for Windows. It presumably createsencrypted partitions (the documentation does not explicitly state this, nor does it state if it supportsthe creation of encrypted container files). You mount the encrypted volume underWindows and it appears as a drive which you can use normally. FreeOTFE supports 'hidden volumes' which areencrypted volumes that are created inside another encrypted volume. All FreeOTFE volumes also have no identifiablesignature. It is compatible with Linux losetup, which is useful if you need to use your encrypted volumes in bothLinux and Windows. Supported ciphers include AES and Twofish, and supported hash algorithms include MD2, MD4, MD5,RIPEMD-128, RIPEMD-160, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512. At the time I write this review, FreeOTFE is stillin BETA testing.
Scramdisk 4 Linux is a suite of Linux tools that allow you to create and access Scramdisk and TrueCrypt containers. It has a Linux driver thatallows you to mount such containers. Scramdisk for Windows and TrueCrypt arefree on-the-fly disk encryption software that you canfind elsewhere on this page.
Cryptainer LE allows you to create 25 MB encrypted containers that appear to Windows as diskdrives. It supports Windows 95 (OSR 2), 98, ME, 2000, XP and 2003. It uses the Blowfishalgorithm. It apparently also allows you to send encrypted emails as well.
(Update: TrueCrypt is no longer maintained nor is the full version available from its official site.The final version found at www.truecrypt.org
[at the time this was written] merely provides the facility for you to copy offyour data from a TrueCrypt encrypted volume, and does not allow you to store any new data. See elsewhere onthis page for successors to thisproject.)TrueCrypt is the successor to E4M (which is no longer maintained). You can use it to encrypt an entire partitionof your hard disk (including your system partition) or to create an encrypted container file which appears likea normal hard disk to Windows. You can then store and access your files on that virtual drive just like any other file.Since the program does not mark the encrypted container (or partition) in any way, there is, theoretically, no wayfor any intruder to guess which file is your encrypted container. This, according to the author, also preservesplausible deniability. Encryption algorithms supported include AES, Blowfish, CAST, IDEA (removed in version 2.1a)and Triple-DES. The source code is available free. This program works under Windows Vista, Windows XP, Mac OS X and Linux.
Free Public Key Encryption Software
Academic Signature is an open source elliptic curve public key encryption program. It offers (quotingdirectly from their website) 'up to 1024 bit ecc, symmetric ciphers up to 4096 bit block length and key length,payload size camouflage, deterministic ECC digital signatures, and zero adversary advantage hybrid ciphers'.Source code and binaries for Windows and Linux (Ubuntu) are available.
GPG, a.k.a. GnuPG, is the GNU version of PGP (Pretty Good Privacy), a public key encryption system. Like all things GNU, it is free and can be freelydistributed and modified. It is generally compatible with the newer PGP versions (depending on theencryption algorithms you choose); but you should read their FAQ for more details.
[Update: this site appears to have disappeared.]The above link is to the International PGP Home Page, where you can get free binaries and sources for Pretty Good Privacy (PGP) for avariety of operating systems for either US or non-US countries. You can use PGP to encrypt your email in conjunction with your emailclient, be it Eudora, ELM, PINE, or whatever. PGP is a public key encryption system, which means that you have two keys(passwords), one which is known only to you and the other is known to your recipient. Messages or documents (or whatever) encoded withone key can only be decoded with the other. You can read more about this from the PGP FAQs at the site.
Free Encryption Software with Steganography

This encryption software allows you to hide your private data such as email messages insidean image (JPG, GIF, TIFF, BMP, etc). The image is still viewable as an image, but it alsocontains the encrypted version of your secret message (steganography). The website does not specify which encryption algorithm is used.

CCrypt is a command line encryption tool that encrypts the files you specify. It is multiplatformwith ports for Windows, Linux, Sun Solaris, Macintosh OS X, FreeBSD, AIX, etc. It uses theRjindael AES cipher (Advanced Encryption Standard). The source code is available.
Free Encryption Programs Windows 10
This program lets you store your serial numbers, passwords, and other types of text notes inan encrypted form (AES 256). It's extremely portable in that it's just a single file that does not have to be installed, and can be placed on a portable medialike a USB flash drive. The data you store is saved into the program file itself meaning that all you need to do to move your data to another locationis to copy the program there. You can also save to a different file, which merely recreates a copy of the program, together with your data, ina new file. The password for your encrypted notes can be set by selecting the 'File' menu followed by the 'Change password...' menu item.The program is open source, released under the GNU General Public License.
