    The function declarations for f_EVP_PKEY_get_raw_private_key() and f_EVP_PKEY_get_raw_public_key() each have a wrong parameter type: outlen: Integer. The correct type is outlen: size_t. On 64-bit, this can lead to memory overwrite if the 64-bit size_t is written to the 32-bit Integer. Reference: https://www.openssl.org/docs/man1.1.1/man3/EVP_PKEY_get_raw_private_key.html Ralf

    f_CRYPTO_get_ex_data should return Pointer, not Integer. The code in question is at OverbyteIcsLIBEAY.pas line 1847, SVN 1476: f_CRYPTO_get_ex_data: function(r: PCRYPTO_EX_DATA; idx: integer): integer; cdecl = Nil; The corresponding C declaration from OpenSSL's crypto.h: void *CRYPTO_get_ex_data(const CRYPTO_EX_DATA *ad, int idx); Suggested solution: f_CRYPTO_get_ex_data: function(r: PCRYPTO_EX_DATA; idx: integer): Pointer; cdecl = Nil; Reference: https://www.openssl.org/docs/man1.1.1/man3/CRYPTO_get_ex_data.html Ralf

    EVP_PKEY_paramgen() pkey should be a double pointer parameter. OverbyteIcsLIBEAY.pas line 1752, SVN 2063: f_EVP_PKEY_paramgen: function(pctx: PEVP_PKEY_CTX; pkey: PEVP_PKEY): Integer; cdecl = Nil; Notice the two ** asterisks in the OpenSSL's evp.h C declaration: int EVP_PKEY_paramgen(EVP_PKEY_CTX *ctx, EVP_PKEY **ppkey); Possible fixes: { More C like: Better if ppkey may be nil. } f_EVP_PKEY_paramgen: function(pctx: PEVP_PKEY_CTX; ppkey: PPEVP_PKEY): Integer; cdecl = Nil; { More Pascal like. Notice that nil cannot be passed this way. } f_EVP_PKEY_paramgen: function(pctx: PEVP_PKEY_CTX; var pkey: PEVP_PKEY): Integer; cdecl = Nil; Reference: https://www.openssl.org/docs/man1.1.1/man3/EVP_PKEY_paramgen.html Ralf

    At the time of this writing, TCryptoExNewFunc is declared as a function while it should be a procedure. OverbyteIcsLIBEAY.pas line 1752, SVN 1476: TCryptoExNewFunc = function(parent: Pointer; ptr: Pointer; ad: PCRYPTO_EX_DATA; idx: integer; argl: DWord; argp: Pointer): Integer; cdecl; This is the corresponding C declaration from OpenSSL's crypto.h, documented here: https://www.openssl.org/docs/man1.1.1/man3/CRYPTO_EX_new.html typedef void CRYPTO_EX_new (void *parent, void *ptr, CRYPTO_EX_DATA *ad, int idx, long argl, void *argp); This is the Pascal translation matching the C declaration: TCryptoExNewFunc = procedure(parent: Pointer; ptr: Pointer; ad: PCRYPTO_EX_DATA; idx: integer; argl: DWord; argp: Pointer); cdecl; Ralf

    OverbyteIcsLIBEAY.pas line 1994 (SVN 1469) declares f_EVP_DigestSignInit() like this: f_EVP_DigestSignInit: function(ctx: PEVP_MD_CTX; pctx: PEVP_PKEY_CTX; etype: PEVP_MD; impl: PEngine; pkey: PEVP_PKEY): Integer; cdecl = Nil; In Pascal, pctx is a single pointer, but C declares pctx as a double pointer: int EVP_DigestSignInit(EVP_MD_CTX *ctx, EVP_PKEY_CTX **pctx, const EVP_MD *type, ENGINE *e, EVP_PKEY *pkey); Following nearby declarations, Pascal should probably change pctx to a var parameter.

    OverbyteIcsLIBEAY.pas line 2336 (SVN 1464) declares f_X509_check_ip_asc() like this: f_X509_check_ip_asc: function(Cert: PX509; Paddress: PAnsiChar; namelen: size_t; flags: Cardinal): Integer; cdecl = nil; This is different from the OpenSSL definition. The Pascal declaration has an extra namelen parameter not present in the C header: int X509_check_ip_asc(X509 *, const char *address, unsigned int flags); Reference: https://www.openssl.org/docs/man1.1.1/man3/X509_check_ip_asc.html Ralf
