#CryptoSecurity101 There isn't a widely established, official hashtag for "cryptosecurity101" as a publication. Hashtags are generally created organically by users or specifically promoted by authors/publishers.

If you are creating a publication and want to establish a hashtag, #CryptoSecurity101 (or a variation like #CryptoSecurityBasics, #CyberSec101Crypto) would be a good choice.

If you are looking for content related to cryptosecurity basics, you would likely find relevant information under:

* #CryptoSecurity

* #CyberSecurity

* #InformationSecurity

* #Cryptography

* #BlockchainSecurity

* #Infosec

* #CyberSec

And if the publication is truly a "101" (introductory) level, then combining one of the above with "101" could work, for example, #CyberSecurity101 or #Cryptography101.

Therefore, while there's no single definitive "publication hashtag," if you need one, I would recommend:

* #CryptoSecurity101

* #Cryptosec101 (shorter)

It depends on whether you are asking for an existing one, or if you are looking to create one.
