SnappyMail Nextcloud 2.35.4 S/Mime Signature gone

[martintm86]

Since the last Update today to 2.35.4 in my Nextcloud the S/Mime Signature feauture have an issue. The button is gone.
I have deleted the data directory and reconfigured my Account with s/mime. But the problem still exists.
Please Fix. If you need more information or if i can Test anything for you please contact me...
Encryption is ok. But without s/Mime signature too...

Your private key is marked in red.
The problem is RSA on the first line as SnappyMail only accepts ENCRYPTED or none-password protected.

snappymail/dev/Model/Identity.js

Line 36 in 190db75

smimeKeyValid: () => /^-----BEGIN (ENCRYPTED )?PRIVATE KEY-----/.test(this.smimeKey()),

RSA is an old PKCS1 format, where without it is PKCS8.
Use openssl pkcs8 -topk8 ... to convert it.

You should set a password for protection, else anyone can use your private key.

If it worked before, i will add RSA in the validity check.

Ok Thank you! Now in pkcs8 anything is ok. A little Error Message will be perfect here...

Well, i just added a "change passphrase" interface for easy converting the insecure RSA keys 😄
Not everyone knows how to (or can) use openssl
