I'm trying to decrypt a file that was encrypted with openssl cms -encrypt -aes256 -binary -stream -outform DER ~/cert.pem and decrypted with openssl cms -decrypt -inform DER -stream -inkey ~/pkey.pem the file is roughly 3.5 GB, and the decrypt fails with 140572959053120:error:07069041:memory buffer routines:BUF_MEM_grow_clean:malloc failure:../crypto/buffer/buffer.c:128: 140572959053120:error:0D06B041:asn1 encoding routines:asn1_d2i_read_bio:malloc failure:../crypto/asn1/a_d2i_fp.c:190: I thought "stream" was suposed to allow bigger files. Am i doing something wrong? or is decrypt broken? Thanks.
