* gpg: Improve passphrase caching.Werner Koch2014-09-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * agent/cache.c (last_stored_cache_key): New. (agent_get_cache): Allow NULL for KEY. (agent_store_cache_hit): New. * agent/findkey.c (unprotect): Call new function and try to use the last stored key. * g10/revoke.c (create_revocation): Add arg CACHE_NONCE and pass to make_keysig_packet. (gen_standard_revoke): Add arg CACHE_NONCE and pass to create_revocation. * g10/keygen.c (do_generate_keypair): Call gen_standard_revoke with cache nonce. -- This patch adds two features: 1. The key for the last passphrase successfully used for unprotecting a key is stored away. On a cache miss the stored away passphrase is tried as well. This helps for the common GPG use case of having a signing and encryption (sub)key with the same passphrase. See the code for more comments. 2. The now auto-generated revocation certificate does not anymore popup a passphrase prompt. Thus for standard key generation the passphrase needs to be given only once (well, two with the confirmation).
* gpg: Change default cipher for --symmetric from CAST5 to AES-128.Werner Koch2014-08-181-2/+9
| | | | | | * g10/main.h (DEFAULT_CIPHER_ALGO): Chhange to AES or CAST5 or 3DES depending on configure option. * g10/gpg.c (main): Set opt.s2k_cipher_algo to DEFAULT_CIPHER_ALGO.
* gpg: Screen keyserver responses.Werner Koch2014-08-141-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * g10/main.h (import_screener_t): New. * g10/import.c (import): Add screener callbacks to param list. (import_one): Ditto. (import_secret_one): Ditto. (import_keys_internal): Ditto. (import_keys_stream): Ditto. * g10/keyserver.c (struct ks_retrieval_screener_arg_s): New. (keyserver_retrieval_screener): New. (keyserver_get): Pass screener to import_keys_es_stream(). -- These changes introduces import functions that apply a constraining filter to imported keys. These filters can verify the fingerprints of the keys returned before importing them into the keyring, ensuring that the keys fetched from the keyserver are in fact those selected by the user beforehand. Signed-off-by: Stefan Tomanek <[email protected]> This is an extended and fixed versions of Stefan's patch. In addition to the changes done in gnupg 2.0, namely the commits 5e933008beffbeae7255ece02383606481f9c169 044847a0e2013a2833605c1a9f80cfa6ef353309 088f82c0b5e39687f70e44d3ab719854e808eeb6 the symbol names have been changed to "screener" to void mixing them up with the iobuf filter feature and it has been changed to be used with the dirmngr based keyserver lookup.

This is useful because for Libgcrypt we specify the algorithm in the S-expressions and the public key ids are not anymore needed. This patch also adds some support for PUBKEY_ALGO_EDDSA which will eventually be used instead of merging EdDSA with ECDSA. As of now an experimental algorithm id is used but the plan is to write an I-D so that we can get a new id from the IETF. Note that EdDSA (Ed25519) does not yet work and that more changes are required. The ECC support is still broken right now. Needs to be fixed. Signed-off-by: Werner Koch <[email protected]>

For example to downloading just the first 32k of a huge file, decrypting that incomplete part and while ignoring all the errors break out the session key. The session key may then be used on the server to decrypt the entire file without the need to have the private key on the server. GnuPG-bug-id: 1389 Signed-off-by: Werner Koch <[email protected]>

Also remove all callers. * common/status.h (STATUS_RSA_OR_IDEA): Remove. Do not emit this status anymore. -- To keep the number of actually used algorithms low, we want to support IDEA only in a basically read-only way (unless --pgp2 is used during key generation). It does not make sense to suggest the use of this old 64 bit blocksize algorithm. However, there is old data available where it might be helpful to have IDEA available.
* Allow creating subkeys using an existing keyWerner Koch2011-11-061-3/+3
| | | | | | This works by specifying the keygrip instead of an algorithm (section number 13) and requires that the option -expert has been used. It will be easy to extend this to the primary key.
* Nuked almost all trailing white space.post-nuke-of-trailing-wsWerner Koch2011-02-041-4/+4
| | | | | | | | We better do this once and for all instead of cluttering all future commits with diffs of trailing white spaces. In the majority of cases blank or single lines are affected and thus this change won't disturb a git blame too much. For future commits the pre-commit scripts checks that this won't happen again.
* Sample ECC keys and message do now work.Werner Koch2011-02-021-0/+1
| | | | | | | | Import and export of secret keys does now work. Encryption has been fixed to be compatible with the sample messages. This version tests for new Libgcrypt function and thus needs to be build with a new Libgcrypt installed.
* Move OpenPGP OID helpers to common/.Werner Koch2011-01-311-4/+0
| | | | | | | This is needed so that the agent will be able to export and import OpenPGP secret keys. Add test case. Removed unused function.
* Reworked the ECC changes to better fit into the Libgcrypt API.Werner Koch2011-01-311-2/+9
| | | | | See ChangeLog for details. Key generation, signing and verification works. Encryption does not yet work. Requires latest Libgcrypt changes.
