* hashers: Change names of SHA2 hash algorithmsTobias Brunner2017-11-171-8/+8
| | | | | Keep the lower case names as they are as we use them internally (parsing and e.g. in OpenSSL as identifier).
* hasher: Add uppercase short names for hash algorithmsTobias Brunner2017-11-172-0/+23

* x509: Initialize signature params when parsing attribute certificatesTobias Brunner2017-11-151-1/+1

|
* unit-tests: Rename targets for libstrongswan and kernel-netlinkThomas Egerer2017-11-091-5/+5
| | | | | | | | | libstrongswan and kernel-netlink are the only two components which do not adhere to the naming scheme used for all other tests. If the tests are run by an external application this imposes problems due to clashing names. Signed-off-by: Thomas Egerer <thomas.egerer@secunet.com>
* auth-cfg: Add RSA/PSS schemes for pubkey and rsa if enabled in strongswan.confTobias Brunner2017-11-082-14/+79
| | | | Also document the rsa/pss prefix.
* Treat RSASSA-PSS keys like rsaEncryption RSA keysTobias Brunner2017-11-083-1/+20
| | | | | | | | | | In theory we should treat any parameters and the identifier itself as restriction to only use the key to create signatures accordingly (e.g. only use RSA with PSS padding or even use specific hash algorithms). But that's currently tricky as we'd have to store and pass this information along with our private keys (i.e. use PKCS#8 to store them and change the builder calls to pass along the identifier and parameters). That would require quite some work.

|
* x509: Add support for signature schemes with parametersTobias Brunner2017-11-085-143/+220
| | | | | Also adds support for specifying the hash algorithm for attribute certificate signatures.

|
* auth-cfg: Store signature schemes as signature_params_t objectsTobias Brunner2017-11-087-48/+92
| | | | | Due to circular references the hasher_from_signature_scheme() helper does not take a signature_params_t object.
* certificate: Return signature scheme and parameters from issued_by() methodTobias Brunner2017-11-0825-72/+119
| | | | | This also required some include restructuring (avoid including library.h in headers) to avoid unresolvable circular dependencies.
* signature-params: Add helper struct for signature scheme and parametersTobias Brunner2017-11-083-18/+319
|
* unit-tests: Add RSA-PSS signature tests with specific saltsTobias Brunner2017-11-081-92/+818

* unit-tests: Warn if we skip RSA tests due to dependenciesTobias Brunner2017-11-081-0/+11
|
* unit-tests: Add ability to issue a warning message for a test caseTobias Brunner2017-11-083-6/+116
| | | | | This way we can warn if we e.g. skipped actually doing something due to dependencies (otherwise the test case would just appear to have succeeded).
* mgf1: Add support for SHA-224/384 based MGF1Tobias Brunner2017-11-082-1/+11

* xof: Add identifiers for MGF1 XOFs based on SHA-224/384Tobias Brunner2017-11-082-5/+13

* gcrypt: Add support for RSA-PSS signaturesTobias Brunner2017-11-083-31/+127
| | | | | | | | For salt lengths other than 20 this requires 0bd8137e68c2 ("cipher: Add option to specify salt length for PSS verification."), which was included in libgcrypt 1.7.0 (for Ubuntu requires 17.04). As that makes it pretty much useless for us (SHA-1 is a MUST NOT), we require that version to even provide the feature.

|
* unit-tests: Add FIPS 186-4 RSASSA-PSS test vectorsTobias Brunner2017-11-081-0/+1629
| | | | | | | | Since not all implementations allow setting a specific salt value when generating signatures (e.g. OpenSSL doesn't), we are often limited to only using the test vectors with salt length of 0. We also exclude test vectors with SHA-1, SHA-224 and SHA-384.

| | | | Excluding SHA-224 and the stuff from FIPS 186-2 (SHA-1, 1024 bit keys).
* gcrypt: Determine missing RSA private key parametersTobias Brunner2017-11-081-4/+133
| | | | | We only need n, e, and d. The primes p and q and the coefficient for the Chinese remainder algorithm can be determined from these.

| | | | | We only need n, e, and d. The parameters for the Chinese remainder algorithm and even p and q can be determined from these.
