Let's Encrypt is a non-profit certificate authority run by Internet Security Research Group (ISRG) that provides X.509 certificates for Transport Layer Security (TLS) encryption at no charge. It is the world's largest certificate authority, [ 3 ] used by more than 400 million websites , [ 4 ] with the goal of all websites being secure and using ...
The Internet Security Research Group (ISRG) is a public-benefit non-profit corporation based in California which focuses on Internet security.

In public-key cryptography and computer security, a root-key ceremony is a procedure for generating a unique pair of public and private root keys. Depending on the certificate policy of a system, the generation of the root keys may require notarization, legal representation, witnesses, or “key-holders” to be present.
A public key infrastructure (PKI) is a set of roles, policies, hardware, software and procedures needed to create, manage, distribute, use, store and revoke digital certificates and manage public-key encryption.
The client sends a CertificateVerify message, which is a signature over the previous handshake messages using the client's certificate's private key. This signature can be verified by using the client's certificate's public key. This lets the server know that the client has access to the private key of the certificate and thus owns the certificate.
Most email software and applications have an account settings menu where you'll need to update the IMAP or POP3 settings. When entering your account info, make sure you use your full email address, including @aol.com, and that the SSL encryption is enabled for incoming and outgoing mail.
The contents of the encrypted device are arbitrary, and therefore any filesystem can be encrypted, including swap partitions. [2] There is an unencrypted header at the beginning of an encrypted volume, which allows up to 8 (LUKS1) or 32 (LUKS2) encryption keys to be stored along with encryption parameters such as cipher type and key size.
