+.Dt EVP 3
+.Os
+.Sh NAME
+.Nm evp
+.Nd high-level cryptographic functions
+.Sh SYNOPSIS
+.Lb libcrypto
+.In openssl/evp.h
+.Sh DESCRIPTION
+The EVP library provides a high-level interface to cryptographic
+functions.
+The abbreviation
+.Dq EVP
+is intended to mean
+.Dq EnVeloPe
+in the sense of
+.Dq wrapper library .
+It is not related to the technical meaning of the term
+.Dq envelope
+in contexts like
+.Xr CMS_encrypt 3 ,
+.Xr EVP_SealInit 3 ,
+.Xr PKCS7_encrypt 3 ,
+or
+.Xr SMIME_write_PKCS7 3 .
+.Pp
+.Xr EVP_SealInit 3
+and
+.Xr EVP_OpenInit 3
+provide public key encryption and decryption to implement digital
+"envelopes".
+.Pp
+The
+.Xr EVP_DigestSignInit 3
+and
+.Xr EVP_DigestVerifyInit 3
+functions implement digital signatures and Message Authentication Codes
+(MACs).
+Also see the older
+.Xr EVP_SignInit 3
+and
+.Xr EVP_VerifyInit 3
+functions.
+.Pp
+Symmetric encryption is available with the
+.Xr EVP_EncryptInit 3
+functions.
+The
+.Xr EVP_DigestInit 3
+functions provide message digests.
+.Pp
+Authenticated encryption with additional data (AEAD) is available with
+the
+.Xr EVP_AEAD_CTX_init 3
+functions.
+.Pp
+The
+.Fn EVP_PKEY_*
+functions provide a high-level interface to asymmetric algorithms.
+To create a new
+.Vt EVP_PKEY ,
+see
+.Xr EVP_PKEY_new 3 .
+.Vt EVP_PKEY Ns s
+can be associated with a private key of a particular algorithm
+by using the functions described in the
+.Xr EVP_PKEY_set1_RSA 3
+page, or new keys can be generated using
+.Xr EVP_PKEY_keygen 3 .
+.Vt EVP_PKEY Ns s
+can be compared using
+.Xr EVP_PKEY_cmp 3
+or printed using
+.Xr EVP_PKEY_print_private 3 .
+.Pp
+The
+.Fn EVP_PKEY_*
+functions support the full range of asymmetric algorithm operations:
+.Bl -bullet
+.It
+For key agreement, see
+.Xr EVP_PKEY_derive 3 .
+.It
+For signing and verifying, see
+.Xr EVP_PKEY_sign 3 ,
+.Xr EVP_PKEY_verify 3 ,
+and
+.Xr EVP_PKEY_verify_recover 3 .
+However, note that these functions do not perform a digest of the
+data to be signed.
+Therefore, normally you would use the
+.Xr EVP_DigestSignInit 3
+functions for this purpose.
+.It
+For encryption and decryption see
+.Xr EVP_PKEY_encrypt 3
+and
+.Xr EVP_PKEY_decrypt 3 ,
+respectively.
+However, note that these functions perform encryption and decryption only.
+As public key encryption is an expensive operation, normally you
+would wrap an encrypted message in a digital envelope using the
+.Xr EVP_SealInit 3
+and
+.Xr EVP_OpenInit 3
+functions.
+.El
+.Pp
+The
+.Xr EVP_BytesToKey 3
+function provides some limited support for password based encryption.
+Careful selection of the parameters will provide a PKCS#5 PBKDF1
+compatible implementation.
+However, new applications should typically not use this (preferring, for
+example, PBKDF2 from PCKS#5).
+.Pp
+The
+.Xr EVP_EncodeInit 3
+family of functions provides base64 encoding and decoding.
