Small correction from my side - "...which is encrypted using bech32 encoding".
Encryption - converting text to text using a secret key. No one who does not know this secret key can decrypt the message.
Encoding - converting one form of text to another but without any key. It's just another representation of the same data and everybody can encode/decode.
bech32 is not encryption, it's encoding. Sorry for that.
My god... Encryption - converting plaintext to ciphertext
