=head1 SYNOPSIS
#include <openssl/evp.h>
- int EVP_PKEY_verifyrecover_init(EVP_PKEY_CTX *ctx);
- int EVP_PKEY_verifyrecover(EVP_PKEY_CTX *ctx,
+ int EVP_PKEY_verify_recover_init(EVP_PKEY_CTX *ctx);

=head1 DESCRIPTION
-The EVP_PKEY_verifyrecover_init() function initializes a public key algorithm
+The EVP_PKEY_verify_recover_init() function initializes a public key algorithm
context using key B<pkey> for a verify recover operation.
-The EVP_PKEY_verifyrecover() function recovers signed data
+The EVP_PKEY_verify_recover() function recovers signed data
using B<ctx>. The signature is specified using the B<sig> and
B<siglen> parameters. If B<rout> is B<NULL> then the maximum size of the output
buffer is written to the B<routlen> parameter. If B<rout> is not B<NULL> then
signing operation. Only certain public key algorithms can recover a signature
in this way (for example RSA in PKCS padding mode).
-After the call to EVP_PKEY_verifyrecover_init() algorithm specific control
+After the call to EVP_PKEY_verify_recover_init() algorithm specific control
operations can be performed to set any appropriate parameters for the
operation.
-The function EVP_PKEY_verifyrecover() can be called more than once on the same
+The function EVP_PKEY_verify_recover() can be called more than once on the same
context if several operations are performed using the same parameters.
=head1 RETURN VALUES
-EVP_PKEY_verifyrecover_init() and EVP_PKEY_verifyrecover() return 1 for success
+EVP_PKEY_verify_recover_init() and EVP_PKEY_verify_recover() return 1 for success
and 0 or a negative value for failure. In particular a return value of -2
indicates the operation is not supported by the public key algorithm.
