If you don't need to compress it, you will still be able to create encrypted containers using the VeraCrypt tool or other software to create encrypted containers.Ī very important detail of using AES, whether in its 128-bit or 256-bit version, is that if your processor supports the AES-NI instruction set, you will be able to encrypt and decrypt files just as quickly. The encryption used by both tools is currently considered secure, however, we must continually compress and decompress the content to access it. By default, ZIP files use AES-256-CTR encryption.Īs you can see, it is very easy to compress a file and encrypt it using 7-Zip and WinRAR programs, two of the most used programs for compressing files.
How to encrypt using 7zip rar#
The bypass function used in RAR 5.X is based on PBKDF2 using HMAC-SHA256. RAR files are encoded with AES-256-CBC for RAR 5.0 format files, and with AES-128-CBC and AES-256-CBC for RAR 4.X files.
How to encrypt using 7zip password#
Then a new window will open where we need to enter the password we want, and we also need to confirm said password.On the screen that appears, we have to select the option that tells us to set a password.You can select the option that best suits you. Then we select the WinRAR icon option that says "add to file" or "add and email".To do this, we need to follow these steps: This program will also allow us to encrypt the contents of the files and folders that we compress, and all this in a very simple and fast way, using the best symmetric encryption algorithms to protect the files. rar format, although this program is chargeable and does not allow us as many compression algorithms as 7-zip. The WinRAR program is also one of the most used to compress files in. The bypass function used is based on PBKDF2 using HMAC-SHA256. If we have selected the option to send by e-mail, the e-mail manager we are using will open automatically.Īs you can see in the previous screenshot, we can select different encryption methods, the most used is AES-256, so just by selecting this option and entering the corresponding password, we can encrypt all files compressed.Then in the encryption section we need to write the encryption password we want.On the screen that appears, we must first select the format of the file we want, that is, in what extension we want to compress it.
Here we can select "add to" or "zip and mail".Then we select the context menu called 7-Zip.We need to right-click the folder we want to compress and protect.To compress a file and encrypt it, just follow these steps:
How to encrypt using 7zip archive#
Thus, you will have to extract the archive with a password, to pull out the archived (and obfuscated) contents.Ī generalized solution that works for all zip programs (WINzip, 7-Zip, MacZip, etc.) is to simply zip it twice making sure the second time (or both) have password protected encryption.The 7-Zip program is one of the most complete programs and used by many users, it is completely free and will allow us to compress and decompress files in different formats, ideal to have a program for all types of compressed files that exist. If you would like to obfuscate the contents of the archive, compress the directory into an archive, and then compress that archive with a password. To simply view the contents of the archive does not require a password. You will be prompted for a password when you try to extract the files. If you need a format that encrypts the file list, use 7Z and make sure you check "Encrypt File Names".įor the more technical minded, the ZIP specification doesn't allow for encryption of the Central Directory. Only the contents of the files is encrypted, which means that no one can read the file without your password.ĭue to this, 7-Zip only asks for your password before unzipping. This means that file lists are viewable by anyone. The ZIP format doesn't allow for encrypting file lists.
