GPG

Sometimes you will encounter similar-looking names such as PGP, OpenPGP, and GPG.

• PGP, short for Pretty Good Privacy, is a 30-year-old commercial encryption software now under the umbrella of Symantec.

• OpenPGP is an encryption standard derived from PGP.

• GPG, the full name is GnuPG, is an open source encryption software based on the OpenPGP standard.

Their cores are similar, and with GPG you are compatible with the others. In security encryption, don't try to reinvent the wheel; GPG, if used in a correct way, can improve security level significantly!

I say all this to ensure that the validity of the applications you download (for example Electrum) must be checked using these tools.
