How much larger are encrypted files?

@infeo

Yes, it gets bigger due to encoding and additional headers for the files .

Very useful information about difference of file dize from encrypted to decrypted, thank you @infeo .

dear @infeo , its possible to know or calculate a percentage about how much files will increase? it will be good to know how many gb a 100gb files will increase after encrypting. thankyou.

You can actually calculate the ciphertext size to the last byte:

• Each encrypted file gets a 88 bytes file header, see: https://docs.cryptomator.org/en/1.5/security/architecture/#file-header-encryption
• Every 32 KiB of data, 48 bytes will be added (nonce + MAC), see: https://docs.cryptomator.org/en/1.5/security/architecture/#file-content-encryption

But to make it simpler, let’s put the file header aside. You can roughly expect a 0,146484375% increase.

A 100 GB file cleartext file will then be roughly a 100.15 GB ciphertext file.

wow. perfect @tobihagemann .
awesome answer, clarify a lot about the free space I need to create and upload huge vaults.
thankyou so much.
