gnupg - gpg: decryption failed: No secret key - Information …
2021年2月1日 · The steps depend on your specific environment, but checking (or creating) the pinentry-program option in ~/.gnupg/gpg-agent.conf is a good place to start. In my case (on OS X with Homebrew-installed gpg and pinentry-mac ) I had …
encryption - What is the default cipher algorithm for GnuPG ...
2015年4月18日 · GnuPG 2.0 also uses CAST5 with the default --gnupg, while this default was changed to AES-128 in GnuPG 2.1: LANG=C gpg2 --verbose --symmetric gpg: using cipher AES (AES without further specification means AES-128 in GnuPG) GnuPG 2.1 uses the same algorithms for the RFC-compliant settings. GnuPG 2.4.5 use AES256 as default symmetric …
gnupg - Which Elliptic curve cryptography (ECC) algorithm to …
2017年5月25日 · I want to generate a key pair with gpg2 2.1.11 and libgcrypt 1.6.5. I use the command gpg2 --expert --full-key-gen. This allows me to choose an ECC: Please select what kind of key you want: (1...
gnupg - Verifying a downloaded file with gpg - Information …
2015年12月18日 · The signature is correct, but GnuPG could not verify the key's validity, thus the signature is not deemed valid. With other words, GnuPG explains you that while the signature is issued by a totally valid key, the key could have issued by anybody (you can create keys for arbitrary mail addresses, there is no central instance verifying them ...
gnupg - What is the most robust available algo for GPG symmetric ...
GnuPG version 2.1 uses AES (128 bit key) as the default, so if you have that version you don't need to tweak the default at all. Older versions default to CAST5, but if they support AES it is worthwhile to override that default. (Neglecting to do so shouldn't be a cause for alarm, however.)
gnupg - gpg decrypt without keyring - Information Security Stack …
2024年11月1日 · GnuPG also provides its features through libraries, especially GPGME and libgcrypt. However, both seem to be useless for your purpose. However, both seem to be useless for your purpose. GPGME still uses keyrings, and libgcrypt is purely a cryptographic library which cannot parse GPG-created files.
GnuPG inner workings (encryption scheme, mode of operation, …
GnuPG implements most of the above; some of the algorithms may be absent, depending on how it was compiled. Most recent pre-compiled GnuPG packages will lack support for the IDEA block cipher (because it was patented until quite recently), but will include support for the block cipher Camellia in addition to the standard ones (despite the fact ...
gnupg - Difference between OpenPGP symmetric encryption and …
2019年7月9日 · I mean if you encrypt a file with an OpenPGP program like GnuPG, using AES-256 symmetric encryption. And do the same with Winzip/7-zip using AES-256. What is the difference? [I am not asking about the asymmetric encryption in OpenPGP with …
Short OpenPGP key IDs are insecure, how to configure GnuPG to …
2015年3月21日 · For example, I have configured GnuPG to always print the 0x-prefixed long key ID by adding a line. keyid-format 0xlong Printing the Fingerprint. Sadly, you cannot set GnuPG to print the whole fingerprint this way, probably because it would break GnuPG's output format for pretty much every screen size. Instead, request it by running
hash - Information Security Stack Exchange
2015年6月1日 · But be aware, that GnuPG will automatically add 3DES, SHA1, uncompressed and those are the minimum set of algorithms all implementations must or should support. If you don't choose any compression algorithm, also ZIP will be added to the list.
