I have changed my laptop's hard drive for a bigger one, and because the installation of elemmentary was corrupted somehow (didn't start the OS)

Now when I mount the hard drive as an external drive, I can't access the data inside the /home folder because it's encrypted, but I don't remember what is the password that I have set to that folder.

Is there any way to "break" the encryption of that folder?

Thanks in advance!

Is there any way to "break" the encryption of that folder?

Yes, there is. This post here seems similar to yours. You should also read the official Ubuntu Documentation about Encrypted /home folder, here: Encrypted home folder

In order to decrypt a whole filesystem: Mount encrypted volumes from command line? See the first answer.

Here is the official Ubuntu Documentation for mounting encrypted external filesystems: EncryptedFilesystemsOnExternalStorage

You should also read about LUKS(Linux Unified Key Setup), the disk encryption system in Linux. Here is a full detailed wiki on LUKS: LUKS: Linux Unified Key Setup
