The resulting key is +then used to initialise the cipher context \fIctx\fR with a cipher \fIcipher\fR for +encryption (\fIen_de\fR=1) or decryption (\fIen_de\fR=0). +.PP +\&\fIpass\fR is an optional parameter and can be NULL. If \fIpasslen\fR is \-1, then the +function will calculate the length of \fIpass\fR using \fBstrlen()\fR. +.PP +\&\fBPKCS5_v2_PBE_keyivgen()\fR and \fBPKCS5_v2_PBE_keyivgen_ex()\fR are similar to the above +but instead use PKCS#5 PBES2 as the encryption algorithm using the supplied +parameters. +.PP +\&\fBPKCS5_v2_scrypt_keyivgen()\fR and \fBPKCS5_v2_scrypt_keyivgen_ex()\fR use SCRYPT as the +key derivation part of the encryption algorithm. +.PP +\&\fIsalt\fR is the salt used in the derivation of length \fIsaltlen\fR. If the +\&\fIsalt\fR is NULL, then \fIsaltlen\fR must be 0. The function will not +attempt to calculate the length of the \fIsalt\fR because it is not assumed to +be NULL terminated. +.PP +\&\fIiter\fR is the iteration count and its value should be greater than or +equal to 1. RFC 2898 suggests an iteration count of at least 1000. Any +\&\fIiter\fR less than 1 is treated as a single iteration. +.PP +\&\fIdigest\fR is the message digest function used in the derivation. +.PP +\&\fIaiv\fR is the initialization vector (IV) to use for the encryption algorithm. +If \fIaiv\fR is NULL, then a random IV will be generated. +.PP +\&\fIprf_nid\fR is the numeric identifier (NID) for the pseudo\-random function to +use with PBKDF2. If \fIprf_nid\fR is not specified (for example, \fIprf_nid\fR is set to 0), +a default PRF is used, which is currently set to SHA\-256 (NID_hmacWithSHA256). +.PP +Functions ending in \fB_ex()\fR take optional parameters \fIlibctx\fR and \fIpropq\fR which +are used to select appropriate algorithm implementations. +.SS "Algorithm Identifier Creation" +.IX Subsection "Algorithm Identifier Creation" +\&\fBPKCS5_pbe_set()\fR, \fBPKCS5_pbe_set_ex()\fR, \fBPKCS5_pbe2_set()\fR, \fBPKCS5_pbe2_set_iv()\fR, +\&\fBPKCS5_pbe2_set_iv_ex()\fR and \fBPKCS5_pbe2_set_scrypt()\fR generate an \fBX509_ALGOR\fR +object which represents an AlgorithmIdentifier containing the algorithm OID and +associated parameters for the PBE algorithm. These functions encode the +key derivation parameters (such as salt and iteration count) and the +encryption parameters (such as the IV) into the ASN.1 structure. +.PP +\&\fBPKCS5_pbkdf2_set()\fR and \fBPKCS5_pbkdf2_set_ex()\fR generate an \fBX509_ALGOR\fR +object which represents an AlgorithmIdentifier containing the algorithm OID and +associated parameters for the PBKDF2 algorithm. +.PP +\&\fBPKCS5_pbe_set0_algor()\fR and \fBPKCS5_pbe_set0_algor_ex()\fR set the PBE algorithm OID and +parameters into the supplied \fBX509_ALGOR\fR. +.PP +If \fIsalt\fR is NULL, then \fIsaltlen\fR specifies the size in bytes of the random salt to +generate. If \fIsaltlen\fR is 0 then a default size is used. +For PBE related functions such as \fBPKCS5_pbe_set_ex()\fR the default salt length is 8 bytes. +For PBE2 related functions that use PBKDF2 such as \fBPKCS5_pbkdf2_set()\fR, +\&\fBPKCS5_pbe2_set_scrypt()\fR and \fBPKCS5_pbe2_set()\fR the default salt length is 16 bytes. +.SH NOTES +.IX Header "NOTES" +The *\fB_keyivgen()\fR functions are typically used in PKCS#12 to encrypt objects. +.PP +These functions make no assumption regarding the given password. +It will simply be treated as a byte sequence. +.SH "RETURN VALUES" +.IX Header "RETURN VALUES" +\&\fBPKCS5_PBE_keyivgen()\fR, \fBPKCS5_v2_PBE_keyivgen()\fR, +\&\fBPKCS5_v2_PBE_keyivgen_ex()\fR, \fBPKCS5_v2_scrypt_keyivgen()\fR, +\&\fBPKCS5_v2_scrypt_keyivgen_ex()\fR, \fBPKCS5_pbe_set0_algor()\fR and +\&\fBPKCS5_pbe_set0_algor_ex()\fR return 1 for success and 0 if an error occurs. +.PP +\&\fBPKCS5_pbe_set()\fR, \fBPKCS5_pbe_set_ex()\fR, \fBPKCS5_pbe2_set()\fR, \fBPKCS5_pbe2_set_iv()\fR, +\&\fBPKCS5_pbe2_set_iv_ex()\fR, \fBPKCS5_pbe2_set_scrypt()\fR, +\&\fBPKCS5_pbkdf2_set()\fR and \fBPKCS5_pbkdf2_set_ex()\fR return an \fBX509_ALGOR\fR object or +NULL if an error occurs. +.SH "CONFORMING TO" +.IX Header "CONFORMING TO" +IETF RFC 8018 (<https://tools.ietf.org/html/rfc8018>) +.SH "SEE ALSO" +.IX Header "SEE ALSO" +\&\fBEVP_PBE_CipherInit_ex\fR\|(3), +\&\fBPKCS12_pbe_crypt_ex\fR\|(3), +\&\fBpassphrase\-encoding\fR\|(7) +.SH HISTORY +.IX Header "HISTORY" +\&\fBPKCS5_v2_PBE_keyivgen_ex()\fR, \fBEVP_PBE_scrypt_ex()\fR, \fBPKCS5_v2_scrypt_keyivgen_ex()\fR, +\&\fBPKCS5_pbe_set0_algor_ex()\fR, \fBPKCS5_pbe_set_ex()\fR, \fBPKCS5_pbe2_set_iv_ex()\fR and +\&\fBPKCS5_pbkdf2_set_ex()\fR were added in OpenSSL 3.0. +.PP +From OpenSSL 3.0 the PBKDF1 algorithm used in \fBPKCS5_PBE_keyivgen()\fR and +\&\fBPKCS5_PBE_keyivgen_ex()\fR has been moved to the legacy provider as an EVP_KDF. +.PP +In OpenSSL 3.2 the default salt length changed from 8 bytes to 16 bytes for PBE2 +related functions such as \fBPKCS5_pbe2_set()\fR. +This is required for PBKDF2 FIPS compliance. +.SH COPYRIGHT +.IX Header "COPYRIGHT" +Copyright 2021\-2026 The OpenSSL Project Authors.
