| 4 | |||
| 5 | EVP_PKEY_copy_parameters, EVP_PKEY_missing_parameters, EVP_PKEY_cmp_parameters, | ||
| 6 | EVP_PKEY_cmp - public key parameter and comparison functions | ||
| 7 | |||
| 8 | =head1 SYNOPSIS | ||
| 9 | |||
| 10 | #include <openssl/evp.h> | ||
| 11 | |||
| 12 | int EVP_PKEY_missing_parameters(const EVP_PKEY *pkey); | ||
| 13 | int EVP_PKEY_copy_parameters(EVP_PKEY *to, const EVP_PKEY *from); | ||
| 14 | |||
| 15 | int EVP_PKEY_cmp_parameters(const EVP_PKEY *a, const EVP_PKEY *b); | ||
| 16 | int EVP_PKEY_cmp(const EVP_PKEY *a, const EVP_PKEY *b); | ||
| 17 | |||
| 18 | =head1 DESCRIPTION | ||
| 19 | |||
| 20 | The function EVP_PKEY_missing_parameters() returns 1 if the public key | ||
| 21 | parameters of B<pkey> are missing and 0 if they are present or the algorithm | ||
| 22 | doesn't use parameters. | ||
| 23 | |||
| 24 | The function EVP_PKEY_copy_parameters() copies the parameters from key | ||
| 25 | B<from> to key B<to>. | ||
| 26 | |||
| 27 | The function EVP_PKEY_cmp_parameters() compares the parameters of keys | ||
| 28 | B<a> and B<b>. | ||
| 29 | |||
| 30 | The function EVP_PKEY_cmp() compares the public key components and parameters | ||
| 31 | (if present) of keys B<a> and B<b>. | ||
| 32 | |||
| 33 | =head1 NOTES | ||
| 34 | |||
| 35 | The main purpose of the functions EVP_PKEY_missing_parameters() and | ||
| 36 | EVP_PKEY_copy_parameters() is to handle public keys in certificates where the | ||
| 37 | parameters are sometimes omitted from a public key if they are inherited from | ||
| 38 | the CA that signed it. | ||
| 39 | |||
| 40 | Since OpenSSL private keys contain public key components too the function | ||
| 41 | EVP_PKEY_cmp() can also be used to determine if a private key matches | ||
| 42 | a public key. | ||
| 43 | |||
| 44 | =head1 RETURN VALUES | ||
| 45 | |||
| 46 | The function EVP_PKEY_missing_parameters() returns 1 if the public key | ||
| 47 | parameters of B<pkey> are missing and 0 if they are present or the algorithm | ||
| 48 | doesn't use parameters. | ||
| 49 | |||
| 50 | These functions EVP_PKEY_copy_parameters() returns 1 for success and 0 for | ||
| 51 | failure. | ||
| 52 | |||
| 53 | The function EVP_PKEY_cmp_parameters() and EVP_PKEY_cmp() return 1 if the | ||
| 54 | keys match, 0 if they don't match, -1 if the key types are different and | ||
| 55 | -2 if the operation is not supported. | ||
