Thank you for your prompt reply Steve, I've already tried to de-base64 first. The DER file is 3.6GB and it fails more or less the same (at least from my point of view): 140690942056104:error:0D06B041:asn1 encoding routines:ASN1_D2I_READ_BIO:malloc failure:a_d2i_fp.c:230: my prinfs show the same numbers as with PEM: asn1_d2i_read_bio is going to grow the buff to 2006569233 asn1_d2i_read_bio is going to grow the buff to 2006573333 asn1_d2i_read_bio is going to grow the buff to 2006577433 asn1_d2i_read_bio is going to grow the buff to 2006581533 ret=OPENSSL_realloc_clean num gets num 2675447504 Passed num == NULL, return the same (double checked now to avoid 5am effects) > If that doesn't help there are other things that can be done, one of which > is to manually extract the decryption key and decrypt the content. A sort > of horribly hacky streaming decrypt. I would do any hack whatever horrible it is to get the file back, unfortunately I am not skilled enough and I can't understand what you suggest. Does pkcs7 consists of "pieces" that can be decoded one by one? -- Michael Tabolsky, Independent IT Professional Milan Area, Italy Italy +393462223547,+3902320626558, Israel +97239150702, UK +441422571312 msn/gtalk/jabber: gf...@gfdsa.org ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
